Summaries for TBC1D3B Gene

Entrez Gene Summary for TBC1D3B Gene

  • This gene encodes a protein that is similar to TBC1 domain family, member 3. This protein contains a TBC (Tre-2, Bub2p, and Cdc16p) domain, which is found in proteins involved in RAB GTPase signaling and vesicle trafficking. There are multiple copies of this gene located within a cluster of chemokine genes on chromosome 17q. [provided by RefSeq, Apr 2009]
