C-myc promoter-binding protein (DENND4A)

The protein contains 1863 amino acids for an estimated molecular weight of 209244 Da.

 

Probable guanine nucleotide exchange factor (GEF) which may activate RAB10. Promotes the exchange of GDP to GTP, converting inactive GDP-bound Rab proteins into their active GTP-bound form. According to PubMed:8056341, it may bind to ISRE-like element (interferon-stimulated response element) of MYC P2 promoter. (updated: Sept. 12, 2018)

The reference OMIM entry for this protein is 600382

Myc promoter-binding protein
Irlb

CLONING

Stasiv et al. (1994) reported the cloning of a cDNA encoding a c-myc promoter-binding protein called IRLB. The predicted amino acid sequence contains a putative alpha-helical DNA binding region. Bacterially expressed protein was shown to bind to the ISRE (interferon-stimulated response element) of the c-myc promoter. ... More on the omim web site
