Caution

Represents an unconventional myosin. This protein should not be confused with the conventional myosin-1 (MYH1).Curated
MYO1A mutations have been reported to cause autosomal dominant non-syndromic hearing loss DFNA48 (PubMed:12736868). It was later shown that MYO1A is not associated with DFNA48 (PubMed:24616153).2 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
