Anti-pleckstrin homology domain containing, family H (with MyTH4 domain) member 3 antibodies enable researchers to detect and measure the pleckstrin homology domain containing, family H (with MyTH4 domain) member 3 antigen in biological samples. This target is a reported synonym of the PLEKHH3 gene, which encodes pleckstrin homology, MyTH4 and FERM domain containing H3. This protein is known to function in signal transduction pathways, among other biological roles. The human version of pleckstrin homology domain containing, family H (with MyTH4 domain) member 3 has a canonical amino acid length of 793 residues and a protein mass of 85.3 kilodaltons, although 4 isoforms have been identified. Other names for this target antigen include pleckstrin homology domain-containing family H member 3, PH domain-containing family H member 3, and pleckstrin homology domain containing, family H (with MyTH4 domain) member 3.
