Summary: Predicted to enable DNA binding activity. Acts upstream of or within several processes, including male genitalia morphogenesis; meiotic nuclear division; and negative regulation of apoptotic process. Located in lateral element. Is expressed in meiotic germ cell of ovary; oocyte; primary oocyte; and spermatocyte. Human ortholog(s) of this gene implicated in spermatogenic failure 1. Orthologous to human SYCP2 (synaptonemal complex protein 2). [provided by Alliance of Genome Resources, Jul 2025]

What's a GeneRIF?

Using yeast two-hybrid screening, it discovered the surprising finding that the SYCP2 NTR associates well with the centromere. It was reported that the C-terminal region of mSYCP2 was found to be responsible for the association of SYCP3 and SYCP1 for synaptonemal complex (SC) formation.
Title: Synaptonemal complex protein 2 (SYCP2) mediates the association of the centromere with the synaptonemal complex.
SYCP2 are not required for centromere cohesion at the metaphase-I stage in male germ cells.
Title: SYCP2 and SYCP3 are required for cohesin core integrity at diplotene but not for centromere cohesion at the first meiotic division.
SYCP2 is a primary determinant of axial elements and lateral elements and, thus, is required for the incorporation of SYCP3 into synaptonemal complexes.
Title: Mouse SYCP2 is required for synaptonemal complex assembly and chromosomal synapsis during male meiosis.
SYCP2 and SYCP3 proteins function in the specificity of chromatin attachment to the chromosome core
Title: Male mouse meiotic chromosome cores deficient in structural proteins SYCP3 and SYCP2 align by homology but fail to synapse and have possible impaired specificity of chromatin loop attachment.
SYCP2 is a primary determinant of axial/lateral elements (AEs/LEs) and is required for the incorporation of SYCP3 into synaptonemal complexes.
Title: Mouse SYCP2 is required for synaptonemal complex assembly and chromosomal synapsis during male meiosis.

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.
