Guanine nucleotide exchange factor VAV2 is a protein that in humans is encoded by the VAV2 gene.^[1][2]

VAV2 is the second member of the VAV oncogene family. Unlike VAV1, which is expressed exclusively in hematopoietic cells, VAV2 transcripts were found in most tissues.^[2]

Interactions

VAV2 has been shown to interact with CD19^[3] and Grb2.^[4][5]
