品种反应性 主要应用 宿主 格式 抗体类型 Ch, H, M, R, B, Ca, Xn WB, ICC Rb Affinity Purified Polyclonal Antibody 描述 产品目录编号 ABE40 描述 Anti-PABPC1/C3 Antibody Alternate Names - Poly(A)-binding protein 1
- Polyadenylate-binding protein 1
- PABP-1
背景信息 Poly(A)-binding proteins, cytoplasmic 1 (PABPC1), and cytoplasmic 3 (PABPC3) are RNA-binding proteins with important roles in post-translational control and metabolism of mRNA. Although both proteins bind to the poly(A) tail of mRNA, PABPC3 binds with a lower affinity than PABPC1. Studies have associated these proteins with tumorigenesis. Decreased expression of PABPC1 in esophageal cancer seems to associate with tumor development and poor prognosis after surgery. PABPC1 can shuttle through the nuclear membrane and is thought to associate with newly synthesized poly(A) transcripts. PABPC1 has also been linked to microRNA mediated silencing when in contact with GW182. PABPC3 is thought to be specific to human testis and controls RNA stability. 产品信息 格式 Affinity Purified 控制 - HeLa cell lysate

Entrez基因汇总 This gene encodes a poly(A) binding protein. The protein shuttles between the nucleus and cytoplasm and binds to the 3' poly(A) tail of eukaryotic messenger RNAs via RNA-recognition motifs. The binding of this protein to poly(A) promotes ribosome recruitment and translation initiation; it is also required for poly(A) shortening which is the first step in mRNA decay. The gene is part of a small gene family including three protein-coding genes and several pseudogenes. 基因符号 - PABPC2

UniProt汇总 FUNCTION: Binds the poly(A) tail of mRNA. May be involved in cytoplasmic regulatory processes of mRNA metabolism such as pre-mRNA splicing. Its function in translational initiation regulation can either be enhanced by PAIP1 or repressed by PAIP2. Can probably bind to cytoplasmic RNA sequences other than poly(A) in vivo. May be involved in translationally coupled mRNA turnover. Implicated with other RNA-binding proteins in the cytoplasmic deadenylation/translational and decay interplay of the FOS mRNA mediated by the major coding-region determinant of instability (mCRD) domain.
SUBUNIT STRUCTURE: Component of a multi subunit autoregulatory ribonucleoprotein complex (ARC), at least composed of IGF2BP1, PABPC1 and CSDE1. Interacts with IGF2BP1. Part of a complex associated with the FOS mCRD domain and consisting of HNRPD, SYNCRIP, PAIP1 and CSDE1/UNR. Interacts with the PABPC1-interacting motif-1 (PAM1) and -2 (PAM2) of PAIP1 and PAIP2. Interacts with PAIP1 with a 1:1 stoichiometry and with PAIP2 with a 1:2 stoichiometry. The interaction with CSDE1 is direct and RNA-independent. Found in a mRNP complex with YBX2.

SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note: Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Shuttles between the cytoplasm and the nucleus.
TISSUE SPECIFICTY: Ubiquitous.
DOMAIN: The RNA-binding domains RRM1 and RRM2 and the C-terminus (last 138 amino acids) regions interact with the PABPC1-interacting motif-1 (PAM1) and -2 (PAM2) of PAIP1, respectively.
The RNA-binding domains RRM2 and RRM3 and the C-terminus (last 138 amino acids) regions interact with the PABPC1-interacting motif-1 (PAM1) and -2 (PAM2) of PAIP2, respectively.
PTM: Methylated by CARM1.
Arg-493 is dimethylated, probably to asymmetric dimethylarginine.
MISCELLANEOUS: Many viruses shutoff host mRNA translational machinery by inhibiting cellular PABPC1 activity using different mechanisms. Picornaviruses, caliciviruses or lentiviruses encode proteases that cleave PABPC1 at several defined sites in the proline-rich linker region between RRMs and the C-terminal domain. Rotaviruses, gammherpesviruses and bunyamwera virus relocalize PABPC1 from the cytoplasm to the nucleus thus altering its function. Many of these viruses translate their mRNA in a PABPC1-independent manner and are unaffected by host PABPC1 inhibition.
SEQUENCE SIMILARITIES: Belongs to the polyadenylate-binding protein type-1 family.
Contains 1 PABC domain.
Contains 4 RRM (RNA recognition motif) domains.
