About DNAJB5

Cytogenetic location: 9p13.3 Genomic coordinates (GRCh38): 9:34,989,745-34,998,900 (from NCBI)

This gene has 12 transcripts (splice variants), 281 orthologues and 11 paralogues. Broad expression in heart (RPKM 17.5), brain (RPKM 13.1) and 21 other tissues.

Summary

This gene encodes a member of the DNAJ heat shock protein 40 family of co-chaperone proteins. The encoded protein contains an N-terminal DNAJ domain and a C-terminal substrate binding domain but lacks the cysteine-rich domain found in Other DNAJ family members. In mice, a multi-protein complex containing this protein, thioredoxin 1, and histone deacetylase 4, serves as a master negative regulator of cardiac hypertrophy. [provided by RefSeq, Mar 2017]
