P80 Katanin, or Katanin p80 (WD repeat containing) subunit B 1, is a human gene encoded by KATNB1. It may also be known as: Katanin p80 WD40 repeat-containing subunit B1; Katanin p80 subunit B1; p80 katanin. The encoded protein has an amino acid length of 655 and a mass of 72.3 kDa. P80 Katanin is a member of the WD repeat KATNB1 family. Homologs of this gene exist in other organisms, including: Rat, Zebrafish, Frog, Chicken.
