  • poly(rC)-binding protein 2
  • Alpha-CP2
Background Information Poly(rC)-binding protein 2 (also known as αCP2 and hnRNP E2) is a part of a highly conserved, widely expressed family of RNA-binding proteins. Every isoform belonging to the Poly(rC)-binding protein family is comprised of a characteristic repeat of three KH domains, a 70 amino acid hnRNP commonly found in a large variety of RNA binding proteins. The KH domain is necessary to the binding of RNA. Poly(rC)-binding protein 2 functions to bind mRNA through its KH domain in a manner that provides a high level of stability to the mRNA. Recent studies have identified 160 mRNAs that are consistently and specifically associated with Poly(rC)-binding protein 2 (Waggoner,2003). Expression of Poly(rC)-binding protein 2 has been observed in all tissues tested.

Entrez Gene Number
Entrez Gene Summary The protein encoded by this gene appears to be multifunctional. Along with PCBP-1 and hnRNPK, it is one of the major cellular poly(rC)-binding proteins. The encoded protein contains three K-homologous (KH) domains which may be involved in RNA binding. Together with PCBP-1, this protein also functions as a translational coactivator of poliovirus RNA via a sequence-specific interaction with stem-loop IV of the IRES, promoting poliovirus RNA replication by binding to its 5'-terminal cloverleaf structure. It has also been implicated in translational control of the 15-lipoxygenase mRNA, human papillomavirus type 16 L2 mRNA, and hepatitis A virus RNA. The encoded protein is also suggested to play a part in formation of a sequence-specific alpha-globin mRNP complex which is associated with alpha-globin mRNA stability. This multiexon structural mRNA is thought to be retrotransposed to generate PCBP-1, an intronless gene with functions similar to that of PCBP2. This gene and PCBP-1 have paralogous genes (PCBP3 and PCBP4) which are thought to have arisen as a result of duplication events of entire genes. Thsi gene also has two processed pseudogenes (PCBP2P1 and PCBP2P2). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq].
