== Disease ==

[https://www.uniprot.org/uniprot/CHIP_HUMAN CHIP_HUMAN] Cerebellar ataxia - hypogonadism. The disease is caused by mutations affecting the gene represented in this entry.

== Function ==

[https://www.uniprot.org/uniprot/CHIP_HUMAN CHIP_HUMAN] E3 ubiquitin-protein ligase which targets misfolded chaperone substrates towards proteasomal degradation. Collaborates with ATXN3 in the degradation of misfolded chaperone substrates: ATXN3 restricting the length of ubiquitin chain attached to STUB1/CHIP substrates and preventing further chain extension. Ubiquitinates NOS1 in concert with Hsp70 and Hsp40. Modulates the activity of several chaperone complexes, including Hsp70, Hsc70 and Hsp90. Mediates transfer of non-canonical short ubiquitin chains to HSPA8 that have no effect on HSPA8 degradation. Mediates polyubiquitination of DNA polymerase beta (POLB) at 'Lys-41', 'Lys-61' and 'Lys-81', thereby playing a role in base-excision repair: catalyzes polyubiquitination by amplifying the HUWE1/ARF-BP1-dependent monoubiquitination and leading to POLB-degradation by the proteasome. Mediates polyubiquitination of CYP3A4. Ubiquitinates EPHA2 and may regulate the receptor stability and activity through proteasomal degradation.<ref>PMID:10330192</ref> <ref>PMID:11146632</ref> <ref>PMID:11557750</ref> <ref>PMID:15466472</ref> <ref>PMID:19103148</ref> <ref>PMID:19567782</ref> <ref>PMID:19713937</ref> <ref>PMID:23990462</ref>
