CCR4-associated factor 4

UniProtKB accession:  P36130

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Involved in mitochondrial fission. Has a partially redundant function to MDV1 in acting as an adapter protein, binding to FIS1 on the mitochondrial outer membrane and recruiting the dynamin-like GTPase DNM1 to form mitochondrial fission complexes. Plays a key role in determining the polarized localization of those DNM1 clusters that are not immediately involved in the mitochondrial fission process.
