DUF1640

DUF1640
PFAM accession number:PF07798
Interpro abstract (IPR024461):

This entry includes coiled-coil domain-containing proteins 90 (CCDC90) and related proteins. CCDC90A was reported to be a regulator of the mitochondrial calcium uniporter (MCU) and hence was renamed MCUR1. However, studies in mammals and in yeast homologue fmp32 have shown that it is a cytochrome c oxidase assembly factor and does not directly regulate MCU [ (PUBMED:25565209) ]. The role of CCDC90B proteins is still not known.

This is a PFAM domain. For full annotation and more information, please see the PFAM entry DUF1640
