Data for: Assessing Protein Sequencing in Human Single Hair Shafts of Decreasing Lengths

Sequences of 15 keratin proteins (i.e., KRT31-36, KRT38-KRT40 and KRT81-84 and KRT86) were downloaded from Uniprot database (version 2016.05.10) and edited to generate a variant keratin protein sequence database. Each variant protein sequence contained a single SAP derived from a nsSNP with a frequency >0.1% in populations of European and African American descent, as listed in the National Center for Biotechnology Information (NCBI) SNP database (http://evs.gs.washington.edu/EVS/).

研究人员从Uniprot数据库（Uniprot database，版本2016.05.10）中下载了15种角蛋白（keratin）的序列，具体包括KRT31-36、KRT38-KRT40、KRT81-84及KRT86，经编辑处理后构建得到变异型角蛋白序列数据库。每一条变异型蛋白序列均包含一处源自非同义单核苷酸多态性（non-synonymous single nucleotide polymorphism, nsSNP）的单氨基酸多态性（single amino acid polymorphism, SAP）；该类多态性在欧洲裔及非裔美国人群体中的出现频率高于0.1%，相关信息收录于美国国家生物技术信息中心（National Center for Biotechnology Information, NCBI）单核苷酸多态性（SNP）数据库（http://evs.gs.washington.edu/EVS/）。
