Gene

CCDC90B is located on chromosome 11 in humans. It is neighbored by:^[5]

• PCF11, a mammalian pre-mRNA cleavage complex 2 protein
• ANKRD42, ankyrin repeat protein involved with calcium ion bonding
• BC070093
• DLG2, a member of the membrane-associated guanylate kinase (MAGUK) family

Protein

Structure

This protein is characterized by the presence of a domain of unknown function, DUF1640. This domain is a characteristic of the entire protein with the exception of the first twenty-three amino acid residues - MNSRQAWRLFLSQGRGDRWVSRP - which are a mitochondrial targeting site and cleaved.

The protein has seven predicted alpha helices, a characteristic of coiled-coil proteins.

Cellular Location

CCDC90B is presumably a mitochondrial protein. It is predicted to contain at least three specific phosphorylation sites: Protein Kinase C Phosphorylation sites, Casein Kinase II Phosphorylation sites, and cAMP/cGMP Dependent Phosphorylation sites.
