Entrez ID 146862
Gene name Unc-45 myosin chaperone B
Gene symbol UNC45B
Synonyms (NCBI Gene)
CMYA4CTRCT43MFM11SMUNC45UNC-45BUNC45
Chromosome 17
Chromosome location 17q12
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
