Welcome to the Mucin Database v.2.2, Oct. 2022

of The Mucin Biology Groups

The HUMAN MUC2 and MUC6 sequences has been updated according the publication Svensson et al., (2018) and MUC3A, MUC3B, and MUC12 in Lang and Pelaseyed (2022) PLOS ONE. Here we provide databases of mucin genes, transcripts, protein sequences and functional domains. The databases are from published mucins and novel mucins found by bioinformatic mining of the available genomes. We hope that this site and its databases will be useful for you!
