Summary: Enables ubiquitin protein ligase activity. Involved in proteasome-mediated ubiquitin-dependent protein catabolic process and regulation of neuron migration. Acts upstream of with a negative effect on reelin-mediated signaling pathway. Acts upstream of or within several processes, including activation of cysteine-type endopeptidase activity involved in apoptotic process; brain development; and intrinsic apoptotic signaling pathway in response to oxidative stress. Located in cytoplasm and nucleus. Part of Cul5-RING ubiquitin ligase complex. Is expressed in central nervous system; eye; and genitourinary system. Orthologous to human RNF7 (ring finger protein 7).

Study in transgenic mice with selective Sag deletion in myeloid lineage found that in contrast to in vitro observations those mice showed increased serum levels of proinflammatory cytokines and enhanced mortality in response to LPS. Sag-/- macrophages released less proinflammatory cytokines, neutrophils released more. Study revealed that Sag plays a differential role in the activation of macrophages and neutrophils.

RBX2, a core component of the E3 ubiquitin ligase CRL5, is essential for retinal layering and function. RBX2 regulates the final cell position of rod bipolar cells, cone photoreceptors and Muller glia. Our data indicate that sustained RELN/DAB1 signaling, triggered by depletion of RBX2 or SOCS7 - a CRL5 substrate adaptor known to recruit DAB1 - causes rod bipolar cell misposition.

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.
