Domain

Polyadenylate-binding protein/Hyperplastic disc protein (IPR002004)

Short name: PABP_HYD

Domain relationships

None.

Description

The polyadenylate-binding protein (PABP) has a conserved C-terminal domain (PABC), which is also found in the hyperplastic discs protein (HYD) family of ubiquitin ligases that contain HECT domains (IPR000569) [PMID: 11287654]. PABP recognises the 3' mRNA poly(A) tail and plays an essential role in eukaryotic translation initiation and mRNA stabilisation/degradation. PABC domains of PABP are peptide-binding domains that mediate PABP homo-oligomerisation and protein-protein interactions. In mammals, the PABC domain of PABP functions to recruit several different translation factors to the mRNA poly(A) tail [PMID: 11940585].
