Summary

DNAJC18 (DnaJ heat shock protein family (Hsp40) member C18, HGNC:28429) is a protein-coding gene on chromosome 5q31.2, encoding DnaJ homolog subfamily C member 18 (Q9H819). (Microbial infection) In case of infection by polyomavirus, involved in the virus endoplasmic reticulum membrane penetration and infection.

Predicted to enable Hsp70 protein binding activity. Predicted to be involved in cellular response to misfolded protein and chaperone cofactor-dependent protein refolding. Located in endoplasmic reticulum membrane.

Function. (Microbial infection) In case of infection by polyomavirus, involved in the virus endoplasmic reticulum membrane penetration and infection. Regulates the recruitment of DNAJB12:DNAJB14 into SV40-induced foci and all cooperate to guide SV40 across the endoplasmic reticulum membrane. The foci represent the site from which SV40 penetrates into the cytosol.

Subcellular location. Endoplasmic reticulum membrane.
