DNAJB4 - DnaJ heat shock protein family (Hsp40) member B4 Gene
Also Known as DjB4; HLJ1; DNAJW
Species: Homo sapiens
About DNAJB4
This gene has 6 transcripts (splice variants), 206 orthologues and 11 paralogues. Ubiquitous expression in adrenal (RPKM 27.3), thyroid (RPKM 23.6) and 25 other tissues.
Summary
The protein encoded by this gene is a molecular chaperone, tumor suppressor, and member of the heat shock protein-40 family. The encoded protein binds the cell adhesion protein E-cadherin and targets it to the plasma membrane. This protein also binds incorrectly folded E-cadherin and targets it for endoplasmic reticulum-associated degradation. This gene is a strong tumor suppressor for colorectal carcinoma, and downregulation of it may serve as a good biomarker for predicting patient outcomes. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2015]
