Pathway Description
G-Protein Signaling Through Tubby Proteins
Mus musculus
Protein Pathway
Tubby protein is a part of a family of proteins called Tubby Like Proteins (TULP) characterized by 260 amino acids that form a helix-filled barrel structure at the carboxylic acid terminal (Tubby domain). Using its Tubby domain to bind phosphatidylinositol 4,5-bisphosphate (PIP2), Tubby proteins are able to localize on the plasma membrane. Through the receptor mediated activation of G-proteins, the enzyme phospholipase C–beta (PLC-beta) hydrolyses PIP2 releasing tubby from the plasma membrane. This triggers protein translocation of tubby to the nucleus allowing tubby to act as a transcription regulator.
