Summary

CEP112 (centrosomal protein 112, HGNC:28514) is a protein-coding gene on chromosome 17q24.1, encoding Centrosomal protein of 112 kDa (Q8N8E3). Recruits mRNAs essential for sperm development, such as CFAP61 and FSIP2 mRNAs, into phase-separated condensates, thereby regulating their translation through a mechanism of liquid-liquid phase separation.

This gene encodes a coiled-coil domain containing protein that belongs to the cell division control protein 42 effector protein family. In neurons, it localizes to the cytoplasm of dendrites and is also enriched in the nucleus where it interacts with the RNA polymerase III transcriptional repressor Maf1 to regulate gamma-aminobutyric acid A receptor surface expression. In addition, the protein has been identified as a component of the human centrosome. Alternative splicing results in multiple transcript variants.
