GENE INFORMATION
Gene name	TBC1D8B (HGNC Symbol)
Synonyms	FLJ20298, RP11-321G1.1
Description	TBC1 domain family, member 8B (with GRAM domain) (HGNC Symbol)
Entrez gene summary	This gene encodes a protein with a TBC (Tre-2/Bub2/CDC16) domain. Some mammalian proteins with this domain have been shown to function as Rab-GAPs by binding to specific Rab proteins and affecting their GTPase activity. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2011]
