TBC1 domain family members 9 and 9B (TBC1D9 and TBC1D9B) Pleckstrin Homology-Glucosyltransferases, Rab-like GTPase activators and Myotubularins (PH-GRAM) domain, repeat 1
TBC1D9 and TCB1D9B may act as a GTPase-activating proteins for Rab family protein(s). TBC1D9 and TCB1D9B contain two N-terminal PH-GRAM domain and a C-terminal Rab-GTPase-TBC (Tre-2, BUB2p, and Cdc16p) domain. This cd contains the first repeat of the PH-GRAM domain. The GRAM domain is found in glucosyltransferases, myotubularins and other putative membrane-associated proteins. The GRAM domain is part of a larger motif with a pleckstrin homology (PH) domain fold.
