Research Backgrounds

Function:

Inhibitory regulator of the Ras-cyclic AMP pathway. Stimulates the GTPase of normal but not oncogenic Ras p21; this stimulation may be further increased in the presence of NCK1.

PTMs:

The N-terminus is blocked.

Phosphorylated by SRC and LCK. The phosphorylation SRC inhibits its ability to stimulate the Ras-GTPase activity, whereas phosphorylation by LCK does not display any effect on stimulation activity.

Subcellular Location:

Cytoplasm.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Tissue Specificity:

In placental villi, detected only in the trophoblast layer (cytotrophoblast and syncytiotrophoblast). Not detected in stromal, endothelial or Hofbauer cells (at protein level).

Subunit Structure:

Interacts with SQSTM1. Interacts with SPSB1; the interaction does not promote degradation. Interacts with CAV2 (tyrosine phosphorylated form). Directly interacts with NCK1. Interacts with PDGFRB (tyrosine phosphorylated). Interacts (via SH2 domain) with the 'Tyr-9' phosphorylated form of PDPK1. Interacts with tyrosine-phosphorylated EPHB4.
