Protein Structure

UniProt Annotation

Function

Guanine nucleotide-releasing protein that binds to SH3 domain of CRK and GRB2/ASH. Transduces signals from CRK to activate RAS. Plays a role in the establishment of basal endothelial barrier function. Plays a role in nerve growth factor (NGF)-induced sustained activation of Rap1 and neurite outgrowth. {ECO:0000269PubMed:17724123, ECO:0000269PubMed:21840392, ECO:0000269PubMed:7806500}.

Subcellular Localization

Early endosome {ECO:0000269PubMed:17724123}.

Disease Associations

Tissue Specificity

Ubiquitously expressed in adult and fetus. Expression is high in adult skeletal muscle and placenta and in fetal brain and heart. Low levels of expression in adult and fetal liver.
