About UNC45B

Cytogenetic location: 17q12 Genomic coordinates (GRCh38): 17:35,147,817-35,189,345 (from NCBI)

This gene has 3 transcripts (splice variants), 218 orthologues, 18 paralogues and is associated with 6 phenotypes. Restricted expression toward heart (RPKM 36.4).

Summary

This gene encodes a co-chaperone required for folding and accumulation of type II myosins. The protein consists of three tetratricopeptide repeat motifs at the N-terminus that form a complex with heat shock protein 90, a central region of unknown function that is conserved in all Unc-45 proteins, and a C-terminal Unc-45/Cro1/She4 domain. The protein is expressed at high levels in striated muscle, where its muscle Myosin chaperone activity is dependent on heat shock protein 90 acting as a co-chaperone. A missense mutation in this gene has been associated with cataract development. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]
