LIG_SH3_3 | PLCB1_HUMAN | 1162 | 1168 | Binary | Pre‑translational | Alternative splicing removes the SH3-binding motif of Isoform B of 1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase beta-1 (PLCB1), abrogating binding to SH3 and multiple ankyrin repeat domains protein 3 (SHANK3). PLCB1 associates with a SHANK3 complex in cardiomyocytes via its splice variant-specific C-terminal tail. Studies show that Isoform B of 1-phosphatidylinositol 4,5-bisphosphate phosphodiesterase beta-1 (PLCB1) selectively mediates downstream responses initiated by Gq-coupled receptors, in particular hypertrophy and apoptosis. | Inferred |
