InnateDB Gene IDBG-54957 (RIC8B)
Protein Structure
UniProt Annotation
Function Guanine nucleotide exchange factor (GEF), which can activate some, but not all, G-alpha proteins by exchanging bound GDP for free GTP. Able to potentiate G(olf)-alpha-dependent cAMP accumulation suggesting that it may be an important component for odorant signal transduction. {ECO:0000250}.
Subcellular Localization Cytoplasm, cell cortex {ECO:0000269PubMed:12652642}. Note=Localizes to the cell cortex.
