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]. * **UniProt Summary**: Acts as a co-chaperone for HSP90 and is required for proper folding of the myosin motor domain. Plays a role in sarcomere formation during muscle cell development. Is necessary for normal early lens development. {ECO:0000250|UniProtKB:Q6DGE9, ECO:0000250|UniProtKB:Q8CGY6}. |UNC45-central| |Hsp90 protein binding| |chaperone-mediated protein folding| |lens development in camera-type eye| |protein folding| |muscle organ development| |camera-type eye development| |eye development| |visual system development| |sensory system development| |muscle structure development| |sensory organ development| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp372|Ibrutinib 1μM R07 exp372]]|1.73| ^Gene^Correlation^ |[[:human genes:p:polr2j3|POLR2J3]]|0.574| Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 3304 * **Expression level (log2 read counts)**: 0.63 {{:chemogenomics:nalm6 dist.png?nolink |}}
