Genes affected

SPATC1L (HGNC:1298): (spermatogenesis and centriole associated 1 like) Enables identical protein binding activity. Predicted to act upstream of or within several processes, including actin polymerization or depolymerization; positive regulation of cAMP-dependent protein kinase activity; and positive regulation of protein kinase A signaling. Predicted to be located in sperm connecting piece. Predicted to be active in centrosome. [provided by Alliance of Genome Resources, Apr 2022]
