PLEKHG1 (Pleckstrin Homology and RhoGEF Domain Containing G1): PLEKHG1 is a gene that encodes a protein containing pleckstrin homology and RhoGEF domains. These domains suggest the protein plays a role in signaling pathways involved in cell morphology, cytoskeletal organization, and cellular migration. While its precise functions are still under study, PLEKHG1 is believed to contribute to the regulation of cytoskeletal dynamics and cell motility.
