Genes affected

SPATA33 (HGNC:26463): (spermatogenesis associated 33) Predicted to act upstream of or within cellular protein localization; fertilization; and flagellated sperm motility. Predicted to be located in sperm mitochondrial sheath. Predicted to be active in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

SPATA33 links:

CHMP1A (HGNC:8740): (charged multivesicular body protein 1A) This gene encodes a member of the CHMP/Chmp family of proteins which are involved in multivesicular body sorting of proteins to the interiors of lysosomes. The initial prediction of the protein sequence encoded by this gene suggested that the encoded protein was a metallopeptidase. The nomenclature has been updated recently to reflect the correct biological function of this encoded protein. Several transcripts encoding different isoforms have been found for this gene.
