Alternative names

  • WW domain binding protein 11 (WBP11)
  • Npw38-binding protein (NpwBP)
  • Splicing factor that Interacts with PQBP-1 and PP1 (SIPP1)
  • SH3 domain binding Protein, 70 kDa (SNP70)

Function

Studies suggest that Wbp11 plays a role in DNA/ RNA transcriptional or post-transcriptional events related to cell division.[3] Wbp11 is found in the nucleus but not the nucleoli of cells in interphase. However it is distributed throughout the cytoplasm in dividing cells.[4] Immunoelectron-microscopy experiments suggest that relocation from a peri-nuclear to a cytoplasmic distribution, coinciding with the onset of mitosis in cell division. Other studies have shown that Wbp11 is a component of the spliceosome. Also, that Wbp11 fragments block pre-mRNA splicing catalysis.[5]

Protein interactions

Wbp11 is a polypeptide known to interact with other WW domain of proteins such as the nuclear protein Npw38 via two proline-rich regions. It associates with Npw38 (hence the name NpwBP) in the nuclei and with Poly(rG) and G-rich ssDNA.[3] The 70kDa protein has also been found to interact with SH3 (Src homology domain 3) domains. The C-terminal proline-rich sequences of SNP70/NpwBP/Wbp11, which binds to the WW domain of Npw38 also fits with both classic type I and type II SH3 binding sequences, hence the name (SNP70).

Wbp11 was found to bind strongly to the tandem SH3 domains of p47phox and to the N-terminal SH3 domain of p47phox, and more weakly to the SH3 domains from c-src and p85α. p47phox.[4]

Furthermore, it has been shown to interact with PP1(protein phosphotase 1), hence the name SIPP1. It has an inhibitory effect to PP1, with its inhibitory potency increasing upon phosphorylation with protein kinase CK1. The binding of Wbp11 with PP1 involves a RVXF (Arg-Val-Xaa-Phe) motif, which functions as a PP1- binding sequence in most interactors of PP1.[5]

A number of other interactions have been indicated such as:

  • Vimentin [4]
  • Growth factor receptor-bound protein 2 (GRB2) [6]
  • Genome polyprotein [7]
  • Tyrosine-protein kinase Fyn [6]
  • Pre-mRNA-processing factor 39 (PRP39) [8]
  • TNF receptor-associated factor 4 (TRAF4) [6]
  • Calcineurin B homologous protein 3 (TESC) [6]
  • Probable ATP-dependent RNA helicase DDX17 [9]
  • CD2 antigen cytoplasmic tail-binding protein 2 (CD2BP2) [10]
  • Poly(rC)-binding protein 1 (PCBP1) [11]

Synonym(s): Rsp5 or WWP domain

The WW domain is a short conserved region in a number of unrelated proteins, which folds as a stable, triple stranded beta-sheet. This short domain of approximately 40 amino acids, may be repeated up to four times in some proteins [PUBMED:7846762, PUBMED:7802651, PUBMED:7828727, PUBMED:7641887]. The name WW or WWP derives from the presence of two signature tryptophan residues that are spaced 20-23 amino acids apart and are present in most WW domains known to date, as well as that of a conserved Pro. The WW domain binds to proteins with particular proline-motifs, [AP]-P-P-[AP]-Y, and/or phosphoserine- phosphothreonine-containing motifs [PUBMED:7644498, PUBMED:11911877]. It is frequently associated with other domains typical for proteins in signal transduction processes.

A large variety of proteins containing the WW domain are known. These include; dystrophin, a multidomain cytoskeletal protein; utrophin, a dystrophin-like protein of unknown function; vertebrate YAP protein, substrate of an unknown serine kinase; Mus musculus (Mouse) NEDD-4, involved in the embryonic development and differentiation of the central nervous system; Saccharomyces cerevisiae (Baker's yeast) RSP5, similar to NEDD-4 in its molecular organisation; Rattus norvegicus (Rat) FE65, a transcription-factor activator expressed preferentially in liver; Nicotiana tabacum (Common tobacco) DB10 protein, amongst others.

This entry represents WW domain-binding protein 11, which may play a role in the regulation of pre-mRNA processing.

Alignments

We store a range of different sequence alignments for families. As well as the seed alignment from which the family is built, we provide the full alignment, generated by searching the sequence database (reference proteomes) using the family HMM. We also generate alignments using four representative proteomes (RP) sets, the UniProtKB sequence database, the NCBI sequence database, and our metagenomics sequence database. More...
