This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.\nSpecies Reactivity: Human, Monkey\n\u003cb\u003eBackground\u003c\/b\u003e\nThe retinoblastoma tumor suppressor protein Rb regulates cell proliferation by controlling progression through the restriction point within the G1-phase of the cell cycle (1). Rb has three functionally distinct binding domains and interacts with critical regulatory proteins including the E2F family of transcription factors, c-Abl tyrosine kinase, and proteins with a conserved LXCXE motif (2-4). Cell cycle-dependent phosphorylation by a CDK inhibits Rb target binding and allows cell cycle progression (5). Rb inactivation and subsequent cell cycle progression likely requires an initial phosphorylation by cyclin D-CDK4\/6 followed by cyclin E-CDK2 phosphorylation (6). Specificity of different CDK\/cyclin complexes has been observed (6-8) and cyclin D1 is required for Ser780 phosphorylation (9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nexon 17 tumor GOS561 substitution mutation causes premature stop; GOS563 exon 17 substitution mutation causes premature stop; OSRC; p105-Rb; p110-RB1; pp110; PPP1R130; pRb; prepro-retinoblastoma-associated protein; protein phosphatase 1, regulatory subunit 130; Rb; RB transcriptional corepressor 1; RB1; retinoblastoma 1; retinoblastoma suspectibility protein; Retinoblastoma-associated protein\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H Mk","brand":"CST","offers":[{"title":"Default Title","offer_id":46800571859113,"sku":"10754V2","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-10754v2","provider":"Iright","version":"1.0","type":"link"}
