Anti-pleckstrin homology domain containing, family G (with RhoGef domain) member 4 antibodies enable researchers to detect and measure the pleckstrin homology domain containing, family G (with RhoGef domain) member 4 antigen in biological samples. This target is a reported synonym of the PLEKHG4 gene, which encodes pleckstrin homology and RhoGEF domain containing G4. This protein is known to function in axon guidance and GPCR signaling pathways, among other biological roles. The human version of pleckstrin homology domain containing, family G (with RhoGef domain) member 4 has a canonical amino acid length of 1191 residues and a protein mass of 130.8 kilodaltons, although 3 isoforms have been identified. Other names for this target antigen include ARHGEF44, PRTPHN1, and SCA4.
