Ras-related protein Rap-2c
Function
Small GTP-binding protein which cycles between a GDP-bound inactive and a GTP-bound active form. May play a role in cytoskeletal rearrangements and regulate cell spreading through activation of the effector TNIK. May play a role in SRE-mediated gene transcription.
Post-translational modifications
Palmitoylated. Palmitoylation is required for association with recycling endosome membranes and activation of TNIK.
Sequence Similarities
Belongs to the small GTPase superfamily. Ras family.
Tissue Specificity
Expressed in liver, skeletal muscle, prostate, uterus, rectum, stomach, and bladder and to a lower extent in brain, kidney, pancreas, and bone marrow. Expressed in mononuclear leukocytes and megakaryocytes.
Cellular localization
- Cytoplasm
- Recycling endosome membrane
- Lipid-anchor
- Cytoplasmic side
