| Product description |
Guanine nucleotide exchange factor (GEF) for Rap1A, Rap2A and M-Ras GTPases. Does not interact with cAMP. PTM:Phosphorylated upon DNA damage, probably by ATM or ATR. Contains 1 cyclic nucleotide-binding domain. Contains 1 N-terminal Ras-GEF domain. Contains 1 PDZ (DHR) domain. Contains 1 Ras-associating domain. Contains 1 Ras-GEF domain. subcellular location:Upon binding to M-Ras, it translocates to the plasma membrane. subunit:Interacts with the second PDZ domain of human PTP1e. tissue specificity:Isoform 3 has highest expression levels in the brain, heart, liver, lung and placenta and is barely detectable in skeletal muscle, kidney and pancreas. |
