Regulator of mitophagy through the upstream regulation of the RNF41/NRDP1-PRKN pathway. Mitophagy is a selective form of autophagy necessary for mitochondrial quality control. The RNF41/NRDP1-PRKN pathway regulates autophagosome-lysosome fusion during late mitophagy. May protect RNF41/NRDP1 from proteosomal degradation, RNF41/NRDP1 which regulates proteosomal degradation of PRKN. Plays a key role in beta cells functions by regulating mitophagy/autophagy and mitochondrial health. Interacts with RNF41/NRDP1. Associates with the endolysosome membrane. Almost exclusively expressed in immune cells, including dendritic cells, B-lymphocytes and natural killer cells. Disease susceptibility is associated with variants affecting the gene represented in this entry. Three common non-coding variants of CLEC16A in strong linkage disequilibrium reach genome-wide significance for association with the disease (PubMed:17632545). The non-coding variant rs12708716 is associated with reduced expression of CLEC16A in beta cells and reduced beta cell function (PubMed:24949970). Belongs to the CLEC16A/gop-1 family. Despite its name, does not contain a C-type lectin domain. Extended N-terminus.
