Summary: Predicted to enable serine-type endopeptidase inhibitor activity. Involved in acrosome assembly. Acts upstream of or within several processes, including male germ cell proliferation; negative regulation of serine-type endopeptidase activity; and seminiferous tubule development. Located in acrosomal vesicle and neuron projection. Is expressed in intestine; male reproductive gland or organ; oviduct; skin; and tongue. Human ortholog(s) of this gene implicated in spermatogenic failure 29. Orthologous to human SPINK2 (serine peptidase inhibitor Kazal type 2). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Overexpression of different variants of Spink2 in D407 tissue culture cells increases their susceptibility to the apoptosis-inducing agent staurosporine in a manner consistent with the differential susceptibility between the DBA/2J and BALB/cByJ strains
Title: Spink2 modulates apoptotic susceptibility and is a candidate gene in the Rgcs1 QTL that affects retinal ganglion cell death after optic nerve damage.
SPINK2 is required for maintaining normal spermatogenesis and potentially regulates serine protease-mediated apoptosis in male germ cells.

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.

Status: VALIDATED

Description

Transcript Variant: This variant (4) differs in the 5' UTR and 5' coding region and uses an alternate splice site in the central coding region, resulting in a frameshift and an early stop codon, compared to variant 1. It encodes isoform 4, which is shorter and has distinct N- and C-termini, compared to isoform 1.
