Function[ARHG7_MOUSE] Acts as a RAC1 guanine nucleotide exchange factor (GEF) and can induce membrane ruffling. May function as a positive regulator of apoptosis. Functions in cell migration, attachment and cell spreading. Promotes targeting of RAC1 to focal adhesions. Downstream of NMDA receptors and CaMKK-CaMK1 signaling cascade, promotes the formation of spines and synapses in hippocampal neurons (By similarity).[1] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe mouse betaPIX-SH3 domain, residues 8-63 of P21-activated kinase interacting exchange factor, has been characterized by X-ray diffraction. Crystals belonging to space group P3(2)21 diffracted to 2.0 A and the structure was phased by the single-wavelength anomalous diffraction method. The domain is a compact beta-barrel with an overall conformation similar to the general SH3 structure. The X-ray structure shows mouse betaPIX-SH3 domain binding the way in which the betaPIX characteristic amino acids do so for an unconventional ligand binding surface. This arrangement provides a rationale for the unusual ligand recognition motif exhibited by mouse betaPIX-SH3 domain. Comparison with another SH3/peptide complex shows that the recognition mode of the mouse betaPIX-SH3 domain should be very similar to the RXXK ligand binding mode. The unique large and planar hydrophobic pocket may contribute to the promiscuity of betaPIX-SH3 domain resulting in its multiple biological functions.
