Name

MELK Gene

maternal embryonic leucine zipper kinase

Enables calcium ion binding activity; non-membrane spanning protein tyrosine kinase activity; and protein serine/threonine kinase activity. Involved in apoptotic process; cell population proliferation; and protein autophosphorylation. Located in cell cortex and plasma membrane. [provided by Alliance of Genome Resources, Mar 2025]

KHDC3L Gene

KH domain containing 3-like, subcortical maternal complex member

The protein encoded by this gene belongs to the KHDC1 family, members of which contain an atypical KH domain that may not bind RNA like canonical KH domains. This gene is specifically expressed in the oocytes, and recent studies suggest that it may function as a regulator of genomic imprinting in the oocyte. Mutations in this gene are associated with recurrent biparental complete hydatidiform mole. [provided by RefSeq, Dec 2011]

TNP2 Gene

transition protein 2 (during histone to protamine replacement)

Predicted to enable zinc ion binding activity. Predicted to be involved in several processes, including penetration of zona pellucida; positive regulation of protein processing; and sperm DNA condensation. Predicted to act upstream of or within binding activity of sperm to zona pellucida and flagellated sperm motility. Predicted to be located in male germ cell nucleus. Predicted to be part of nucleosome. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Mar 2025]

TNP1 Gene

transition protein 1 (during histone to protamine replacement)

Transition protein-1 is a spermatid-specific product of the haploid genome which replaces histone and is itself replaced in the mature sperm by the protamines (see PRM1, MIM 182880; PRM2, MIM 182890) (Luerssen et al., 1990 [PubMed 2249851]).[supplied by OMIM, Mar 2008]

LOC643855 Gene

G1 to S phase transition pseudogene

GSPT2 Gene

G1 to S phase transition 2

This gene encodes a GTPase that belongs to the GTP-binding elongation factor family. The encoded protein is a polypeptide release factor that complexes with eukaryotic peptide chain release factor 1 to mediate translation termination. This protein may also be involved in mRNA stability.[provided by RefSeq, Mar 2010]

GSPT1 Gene

G1 to S phase transition 1

Enables GTPase activity and translation release factor activity. Involved in regulation of translational termination and translational termination. Acts upstream of or within protein methylation. Part of translation release factor complex. Is active in cytosolic ribosome. [provided by Alliance of Genome Resources, Mar 2025]

TZMP1 Gene

transition zone microprotein 1
