title: Nucleotide sequences of pigeon feather keratin genes.
abstract: We analyzed two pigeon feather keratin clones from a cosmid pigeon genomic library. Each of the clones contained three feather keratin genes that had the same general structure: a 5' non-coding region separated by an intron, a protein-coding region encoding a protein of 100 amino acids, and a 3' non-coding region. Length and transcriptional organization of the genes were variable. The length variation, about 1.2-3.7 kb, was mainly due to the difference in the length of the 3' non-coding region, and the longer genes had opposite transcriptional organization in contrast to the shorter genes. The nucleotide sequences of the coding region were very similar among the six genes but not the same.
