Keratin, type I cuticular Ha1 is a protein that in humans is encoded by the KRT31 gene.[5][6][7]

Function

The protein encoded by this gene is a member of the keratin gene family. As a type I hair keratin, it is an acidic protein which heterodimerizes with type II keratins to form hair and nails. The type I hair keratins are clustered in a region of chromosome 17q12-q21 and have the same direction of transcription.[7]

Model organisms

Model organisms have been used in the study of KRT31 function. A conditional knockout mouse line called Krt31^{tm1e(KOMP)Wtsi} was generated at the Wellcome Trust Sanger Institute.[8] Male and female animals underwent a standardized phenotypic screen[9] to determine the effects of deletion.[10][11][12][13] Additional screens performed: - In-depth immunological phenotyping[14]
