|Application ||WB, IHC-P, IF, E|
|Reactivity||Human, Mouse, Rat|
|Dilution||IF (20 µg/ml), IHC-P (5 µg/ml), WB (1-2 µg/ml)|
|Other Names||Rap guanine nucleotide exchange factor 4, Exchange factor directly activated by cAMP 2, Exchange protein directly activated by cAMP 2, EPAC 2, cAMP-regulated guanine nucleotide exchange factor II, cAMP-GEFII, RAPGEF4, CGEF2, EPAC2|
|Target/Specificity||Human RAPGEF4 / EPAC2. At least two isoforms of EPAC2 are known to exist; this antibody will detect only the larger isoform.|
|Reconstitution & Storage||Short term 4°C, long term aliquot and store at -20°C, avoid freeze thaw cycles. Store undiluted.|
|Precautions||RAPGEF4 / EPAC2 Antibody (N-Terminus) is for research use only and not for use in diagnostic or therapeutic procedures.|
|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 (By similarity).|
|Cellular Location||Cytoplasm. Membrane; Peripheral membrane protein|
|Tissue Location||Predominantly expressed in brain and adrenal gland. Isoform 2 is expressed in liver. Isoform 1 is expressed in liver at very low levels|
