Recombinant Human Rap guanine nucleotide exchange factor 4 (RAPGEF4), Truncated

Uniprot Id

Q8WZA2

Target Species

Human

Target Name

RAPGEF4

Target Full Name

Rap guanine nucleotide exchange factor 4

Target Function

Guanine nucleotide exchange factor (GEF) for RAP1A, RAP1B and RAP2A small GTPases that is activated by binding cAMP. Seems not to activate RAB3A. Involved in cAMP-dependent, PKA-independent exocytosis through interaction with RIMS2.

Target Subcellular Location

Cytoplasm. Membrane; Peripheral membrane protein.

Target Tissue Specificity

Predominantly expressed in brain and adrenal gland. Isoform 2 is expressed in liver. Isoform 1 is expressed in liver at very low levels.

Target Background

Enables guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of neurotransmitter receptor localization to postsynaptic specialization membrane and regulation of postsynapse organization. Predicted to act upstream of or within adenylate cyclase-activating G protein-coupled receptor signaling pathway; regulation of exocytosis; and secretion by cell. Predicted to be located in plasma membrane. Predicted to be active in glutamatergic synapse; hippocampal mossy fiber to CA3 synapse; and postsynaptic density. Implicated in autistic disorder.
