Studies have also shown that it will negatively regulate nitric oxide production, and also that it functions to limit cellular toxicity in activated macrophages.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eSPRY Domain-Containing SOCS Cox Mechanism\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eIt does this by mediating the ubiquitination and proteasomal degradation of NOS2. It can also act as a bridge, which helps to link NOS2 with the ECS E3 ubiquitin ligase complex components ELOC and CUL5. Researchers have also found that the protein can play a role in the pathway protein ubiquitination, which forms part of the protein modification. It has been shown to be essential for cell viability.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eSPSB Activity\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eIn terms of catalytic activity, there is cleavage of hydrophobic, n-terminal signal or leader sequences, which come from the secreted and periplasmic proteins.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eSPRY Domain-Containing SOCS Cox Structure\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eIn terms of structure, the SPSB is a component of the probable ECS E3 ubiquitin -protein ligase complex, which contains CUL5, RNF7\/RBX2, elongin BC complex, and SPSB1.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eSPSB Interactions\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eIt has been shown to interact with ELOC, ELOB, RNF7, and CUL5. Researchers have observed that it interacts in a direct way with the MET tyrosine kinase domain, both in the presence of HGF as well as the absence of HGF. HGF treatments have been shown to have a positive impact on the interaction. It also interacts with PAWR -- this interaction occurs in association with the Elongin BC complex. Also interacts with NOS2.\u003c\/p\u003e","products":[{"product_id":"spsb1-human","title":"SPSB1 Human","description":"\u003cp\u003eSPRY Domain-Containing SOCS Cox Protein 1 Human Recombinant\u003c\/p\u003e\n\n\u003cdiv class=\"synonyms_hide\"\u003e\n  \u003cp\u003eSPRY domain-containing SOCS box protein 1, SSB-1, SPSB1, SSB1.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"prospecbio","offers":[{"title":"2µg","offer_id":43174371360852,"sku":"PRO-223","price":60.0,"currency_code":"USD","in_stock":true},{"title":"10µg","offer_id":43174371393620,"sku":"PRO-223","price":145.0,"currency_code":"USD","in_stock":true},{"title":"1mg","offer_id":43174371426388,"sku":"PRO-223","price":5200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0559\/3219\/0804\/files\/Prospecbio-spsb1-human-PRO-223.png?v=1776710854"},{"product_id":"spsb2-human","title":"SPSB2 Human","description":"\u003cp\u003eSPRY Domain-Containing SOCS Cox Protein 2 Human Recombinant\u003c\/p\u003e\n\n\u003cdiv class=\"synonyms_hide\"\u003e\n  \u003cp\u003eSPRY domain-containing SOCS box protein 2, SSB-2, Gene-rich cluster protein C9, SPSB2, GRCC9, SSB2, GRCC9.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"prospecbio","offers":[{"title":"5µg","offer_id":43174372278356,"sku":"PRO-1264","price":60.0,"currency_code":"USD","in_stock":true},{"title":"20µg","offer_id":43174372311124,"sku":"PRO-1264","price":145.0,"currency_code":"USD","in_stock":true},{"title":"1mg","offer_id":43174372343892,"sku":"PRO-1264","price":2700.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0559\/3219\/0804\/files\/Prospecbio-spsb2-human-PRO-1264.png?v=1776710859"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0559\/3219\/0804\/collections\/Image_5b01282e-62fd-431a-9b22-a5dbdfeff7ba.png?v=1700647909","url":"https:\/\/prospecbio.com\/collections\/spsb.oembed","provider":"prospecbio","version":"1.0","type":"link"}
