forkhead associated (FHA) domain found in Saccharomyces cerevisiae pre-mRNA leakage protein 1 (PML1) and similar proteins
PML1 is an FHA domain-containing protein required for efficient splicing and pre-mRNA nuclear retention. It is a component of the pre-mRNA retention and splicing (RES) complex composed of at least BUD13, IST3, and PML1. It contains an FHA domain, which is a small phosphopeptide recognition module.
Feature 1:putative phosphopeptide binding site [polypeptide binding site]
Evidence:
Comment:GR at the C terminus of strand beta3, SRxH just preceding beta5, and motif SxNG in the beta6-beta7 turn indicate a canonical mode of pThr recognition.
