Summary: Predicted to enable identical protein binding activity and protein-membrane adaptor activity. Predicted to be involved in nuclear envelope organization. Predicted to act upstream of or within cell differentiation and spermatogenesis. Predicted to be located in microtubule. Predicted to be part of meiotic nuclear membrane microtubule tethering complex. Predicted to be active in nuclear envelope. Is expressed in brainstem; genitourinary system; and submandibular gland. Orthologous to human SPAG4 (sperm associated antigen 4). [provided by Alliance of Genome Resources, Apr 2022]

GeneRIFs: Gene References Into Functions

What's a GeneRIF?

The results thus indicate that SPAG4, albeit not essential for the formation of the HTCA per se, is, nevertheless, required for tightening the sperm head-to-tail anchorage by provoking the correct attachment of the lateral parts of the basal plate to the implantation fossa.
Title: Ultra-structure of the sperm head-to-tail linkage complex in the absence of the spermatid-specific LINC component SPAG4.
SUN4, a spermatid nuclear membrane protein has an essential function in coupling the manchette to the nuclear periphery.
Title: SUN4 is essential for nuclear remodeling during mammalian spermiogenesis.

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.
