UNC45B (unc-45 myosin chaperone B)

Gene

• Entrez ID: 146862
• Gene name: Unc-45 myosin chaperone B
• Gene symbol: UNC45B
• Synonyms: CMYA4, CTRCT43, MFM11, SMUNC45, UNC-45B, UNC45
• 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
