The gene Ras-specific guanine nucleotide-releasing factor-2 (RASGRF2) is mapped to human chromosome 5q13. It belongs to a family of calcium/calmodulin-regulated guanine-nucleotide exchange factors. RASGRF2 transcripts are abundantly expressed in human brain tissue. Low levels of RASGRF2 are also detected in human heart, placenta, kidney, pancreas, human ovary and spleen tissues. The protein localizes to the cytoplasm. However, depending upon the interaction partner it can translocate to the cell periphery. RasGRF2 protein contains two pleckstrin homology (PH) regions, a coiled-coil motif, a Ca2+/calmodulin binding ilimaquinone (IQ) domain, a Dbl homology (DH) region and the prototypical Cdc25 (Ras-specific guanine nucleotide-releasing factor 1) Ras exchange domain.
Synonyms: Anti-Guanine nucleotide-releasing factor 2; Anti-Ras guanine nucleotide exchange factor 2; Anti-Ras-GRF2; Anti-Ras-specific guanine nucleotide-releasing factor 2

Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: In neurons, p35/CDK5 (cyclin-dependent like kinase 5) phosphorylates Ras-specific guanine nucleotide-releasing factor-2 (RASGRF2), thereby modulating Rac-dependent extracellular signal-regulated kinase (ERK1/2) activity and microtubule-associated protein-1b distribution. RASGRF2 is also involved in T-cell signaling. Presence of RASGRF2 in T-cells activates Ras and stimulates the transcriptional factor NF-AT (nuclear factor of activated T cells).
