TBC1 domain family member 3F (TBC1D3F)

Function

• acts as a GTPase activating protein for RAB5
• does not act on RAB4 or RAB11 (putative)
• ubiquitinated by a CUL7-based E3 ligase, which leads to proteasomal degradation
• palmitoylation is required for membrane localization & protects TBC1D3 from ubiquitination

Structure

• contains 1 Rab-GAP TBC domain

Compartment

• cell membrane, lipid-anchor
• associated with lipid rafts

Expression

• expressed in most tissues including pancreas, thymus & testis

Genetics

• TBC1D3 is encoded by a collection of very similar paralogs with multiple copies of each paralog
• some human genomes encoding > 50 copies depending on ethnic origin of the donor

More general terms

• TBC1 domain family member
