Summary: Predicted to enable several functions, including F-box domain binding activity; beta-catenin binding activity; and cullin family protein binding activity. Predicted to contribute to ubiquitin-protein transferase activity. Involved in SCF-dependent proteasomal ubiquitin-dependent protein catabolic process. Acts upstream of or within protein K48-linked ubiquitination and protein monoubiquitination. Located in centrosome and cytosol. Part of Cul7-RING ubiquitin ligase complex and SCF ubiquitin ligase complex. Is expressed in several structures, including central nervous system; early conceptus; genitourinary system; notochord; and sensory organ. Orthologous to human SKP1 (S-phase kinase associated protein 1). [provided by Alliance of Genome Resources, Oct 2024]

miR-582-5p targets Skp1 and regulates NF-kappaB signaling-mediated inflammation.
Title: miR-582-5p targets Skp1 and regulates NF-κB signaling-mediated inflammation.
Loss of SKP1 prior to meiosis leads to aberrant localization of DSB repair proteins and a failure in synapsis initiation in meiosis of both males and females as well as a defect in sister chromatid cohesion. FBXO47 interacts with SKP1 and HORMAD1 and targets HORMAD1 for polyubiquitination and degradation in HEK293T cells.
Title: SCF ubiquitin E3 ligase regulates DNA double-strand breaks in early meiotic recombination.
SKP1 localizes to synapsed chromosome axes and evicts HORMAD proteins from these regions in meiotic spermatocytes. SKP1 maintains synapsis in meiosis of both sexes. SKP1-deficient spermatocytes display premature desynapsis, precocious pachytene exit, loss of PLK1 and BUB1 at centromeres. SKP1-deficient spermatocytes show sharply reduced MPF activity and fail to enter MI despite treatment with okadaic acid.
Title: SKP1 drives the prophase I to metaphase I transition during male meiosis.
Consistent with Skp1a functioning through regulation of Nmnat2, Skp1a knockdown fails to protect axons from Nmnat2 knockdown.

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.
