Also known as: SGY; SGY1; mSgy; SGY-1; Soggy
Summary: Predicted to enable co-receptor binding activity and receptor antagonist activity. Involved in negative regulation of testosterone biosynthetic process; penetration of zona pellucida; and positive regulation of apoptotic process. Acts upstream of or within canonical Wnt signaling pathway and positive regulation of fat cell differentiation. Located in acrosomal vesicle. Is expressed in several structures, including extraembryonic component and reproductive system. Orthologous to human DKKL1 (dickkopf like acrosomal protein 1).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
