MC1R gene sequence

Sequence variations in the melanocortin 1 receptor (MC1R) gene are associated with melanism in many different species of mammals, birds, and reptiles. The gray squirrel ( Sciurus carolinensis ), found in the British Isles, was introduced from North America in the late 19th century We sequenced the melanocortin-1 receptor (Mc1r) to study the genetic basis of color polymorphism in a group of snake species with variable black banding, the genera Sonora, Chilomeniscus, and Chionactis. Mc1r is an important gene in the melanin synthesis pathway and is associated with ecologically important variation in color pattern in birds,. Melanocortin 1 Receptor (MC1R) Gene Sequence Variation and Melanism in the Gray (Sciurus carolinensis), Fox (Sciurus niger), and Red (Sciurus vulgaris) Squirre MC1R (Melanocortin 1 Receptor) is a Protein Coding gene. Diseases associated with MC1R include Melanoma, Cutaneous Malignant 5 and Skin/Hair/Eye Pigmentation, Variation In, 2.

MC1R is one of the key proteins involved in regulating mammalian skin and hair color. It is located on the plasma membrane of specialized cells known as melanocytes, which produce the pigment melanin through the process of melanogenesis Genetic variants in MC1R define the skin/hair/eye pigmentation variation locus 2 (SHEP2) [MIM i:266300]. Hair, eye and skin pigmentation are among the most visible examples of human phenotypic variation, with a broad normal range that is subject to substantial geographic stratification

the MC1R gene was directly sequenced and their associations with cutaneous melanoma (CM) risk was assessed in a hospital-based study of 1106 patients with CM and control subjects in Texas; 61 MC1R variants were identified; Association of melanocortin 1 receptor gene polymorphisms with skin reflectance and freckles in Japanes Mc1r was variable, with 4.4% maximum sequence divergence across Chilomeniscus, Chionactis, and Sonora. Maximum sequence divergence within the genus Sonora was also 4.4%, and 2.7% within S. semiannulata. We found that amino acid variation was minimal DNA sequencing of guppy MC1R and MC1R polymorphism We determined the complete coding sequence and partial untranslated regions of the guppy MC1R gene. The complete coding sequence of the guppy MC1R gene contains 969 bp (+), which is predicted to encode a protein of 322 amino acids

The human MC1R gene is highly polymorphic; therefore, we sequenced the entire MC1R coding region of 1122 bp in 181 depressed Mexican-American patients and 185 Mexican-American controls The black-bellied vole (Eothenomys melanogaster) with complete melanic and brown forms provides an outstanding opportunity to study the genetic polymorphism underpinning color variation. Mutations in the coding region of melanocortin 1 receptor (Mc1r) have been shown to cause color variation in a wide range of species

Pheomelanin The mutations in the Mc1r gene change the amino acid sequence of the MC1R protein and this all changes the structure of the protein Most people with red hair have it because of a known alteration, or mutation, in the gene for a protein called the melanocortin-1 receptor (MC1R). If you have one or two copies of the unaltered MC1R gene, you will have brown or black hair. But if you have two copies of the altered gene, you'll have red hair

The ligand that binds to MC1R is alpha melanocyte stimulating hormone, abbreviated α-MSH, a small peptide 13 amino acids long, produced by specialized cells in the anterior pituitary gland (de Duve, 1984). When α-MSH binds to MC1R in the cell membrane of a melanocyte, the gene that codes for tyrosinase is turned on Furthermore, the sequence result of MC1R gene at position 147 clearly showed that there are two types genotype: Heterozygote (T/C) for Bali cattle and homozygote (T/T) for Aceh cattle . Thus, the mutation T instead of C was called as subsitution 147C→T. There were also indel mutation as shown in Fig. 3c and d (162indelG) Sequence Polymorphism in the MC1R Gene We obtained 741 bp fragments of MC1R gene in this study. Three SNPs (G199A, G225A, and A466G) were detected from MC1R gene: one of them was synonymous and two of them were leading to amino acid substitution (Asp67Asn and Thr156Ala). All of these SNPs were newly reported Melanocortin 1 receptor (MC1R), the agouti signaling protein (ASIP), and tyrosinase related protein 1 (TYRP1) are among the major regulators of pigmentation in mammals. Recently, MC1R and ASIP sequence variants were associated with white and black/dark brown coat colors, respectively, in the dromedary Given the multiple relevant roles of MC1R, we studied whether the MC1R gene would be associated with susceptibility to major depressive disorder or with response to antidepressant treatment. Methods: The human MC1R gene is highly polymorphic; therefore, we sequenced the entire MC1R coding region of 1122 bp in 181 depressed Mexican-American patients and 185 Mexican-American controls

2.2. Amplification of the MC1R Gene and Sequencing. Genomic DNA was extracted by a standard phenol/ chloroform method. The whole coding region of MC1R gene was amplified using a primer pair (forward: 5′-GGACCCTGAGAGCAAGCAC-3′; reverse 5′-CTCACCTTCAGGGATGGTCTA-3′) designed using the cattle sequence (GenBank accession number NM_174108). The amplified fragment length was 1085 bp. MC1R is a G protein-coupled receptor that is highly expressed in melanocytes, the specialized cells that are the site of pigment production. A peptide hormone, α-melanocyte-stimulating hormone, typically activates MC1R, resulting in elevated levels of cAMP and increased production of eumelanin Sequence variations in the melanocortin-1 receptor (MC1R) gene are associated with melanism in many different species of mammals, birds and reptiles. The grey squirrel (Sciurus carolinensis), found in the British Isles, was introduced from North America in the late nineteenth century. Melanism in the British grey squirrel is associated with a 24 base pair deletion in the MC1R

The expression of this gene, however, is controlled by various other genes. The melanocortin 1 receptor (MC1R) gene in its normal form produces pheomelanin and converts it into eumelanin. In the event of mutation, the amount of pheomelanin builds up, and is not converted into.
