  Domain Name: BAR_Rich1
The Bin/Amphiphysin/Rvs (BAR) domain of RhoGAP interacting with CIP4 homologs protein 1. BAR domains are dimerization, lipid binding and curvature sensing modules found in many different proteins with diverse functions. RhoGAP interacting with CIP4 homologs protein 1 (Rich1) is also called Neuron-associated developmentally-regulated protein (Nadrin) or Rho GTPase activating protein 17 (ARHGAP17). It is a Cdc42- and Rac-specific GAP that binds to polarity proteins through the scaffold protein angiomotin and plays a role in maintaining the integrity of tight junctions. It may be a component of a sorting mechanism in the recycling of tight junction transmembrane proteins. Rich1 contains an N-terminal BAR domain followed by a Rho GAP domain and a C-terminal proline-rich domain. It interacts with the BAR domain proteins endophilin and amphiphysin through its proline-rich region. The BAR domain of Rich1 forms oligomers and can bind membranes and induce membrane tubulation.
No pairwise interactions are available for this conserved domain.
