External Ids for VPS39 Gene
This gene encodes a protein that may promote clustering and fusion of late endosomes and lysosomes. The protein may also act as an adaptor protein that modulates the transforming growth factor-beta response by coupling the transforming growth factor-beta receptor complex to the Smad pathway. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]
GeneCards Summary for VPS39 Gene
VPS39 (Vacuolar Protein Sorting 39 Homolog (S. Cerevisiae)) is a Protein Coding gene. An important paralog of this gene is TGFBRAP1.
UniProtKB/Swiss-Prot for VPS39 Gene
May play a role in clustering and fusion of late endosomes and lysosomes. Regulator of TGF-beta/activin signaling, inhibiting SMAD3- and activating SMAD2-dependent transcription. Acts by interfering with SMAD3/SMAD4 complex formation, this would lead to inhibition of SMAD3-dependent transcription and relieve SMAD3 inhibition of SMAD2-dependent promoters, thus increasing SMAD2-dependent transcription. Does not affect TGF-beta-induced SMAD2 or SMAD3 phosphorylation, nor SMAD2/SMAD4 complex formation.
