PABP1 has been shown to have multiple functions, including translation initiation, mRNA stabilization, and mRNA turnover (3,4). Phosphorylation of PABP has been shown to enhance RNA binding in eukaryotes, and PABP1 has been shown to shuttle between the nucleus and cytoplasm (5,6). PABP1 is methylated on Arg455 and Arg460 by the CARM1 protein methyltransferase (7,8); however, the function of this methylation has yet to be determined.\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nPAB1; PABP; PABP 1; PABP-1; PABP1; PABPC1; PABPC2; PABPL1; poly(A) binding protein cytoplasmic 1; poly(A) binding protein, cytoplasmic 1; poly(A) binding protein, cytoplasmic 2; Poly(A)-binding protein 1; Polyadenylate-binding protein 1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M R Mk\nSENSITIVITY: Endogenous\nMW (kDa): 71\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46801025171625,"sku":"61796S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-61796s","provider":"Iright","version":"1.0","type":"link"}
