Bridging integrator 2 (Bin2) is a BAR domain containing protein that is mainly expressed in haematopoietic cells [1]. It promotes cell motility and migration, probably via its interaction with the cell membrane and with podosome proteins that mediate interaction with the cytoskeleton. Bin2 modulates membrane curvature, mediates membrane tubulation and it plays a role in podosome formation. This entry represents the C-terminal tail which mediates interactions with SH3 domains, through its proline-rich regions functioning as an adaptor for SH3 domain-containing proteins at podosomes. This domain is rich in glutamates, serines and prolines. It contains two consensus PxxP sequences (PTSPR and PEKPVR) [1].
BAR domains are dimerisation, lipid binding and curvature sensing modules found in many different protein families. A BAR domain with an additional N-terminal amphipathic helix (an N-BAR) can drive membrane curvature. These N-BAR domains are found in ...
BAR domains are dimerisation, lipid binding and curvature sensing modules found in many different protein families. A BAR domain with an additional N-terminal amphipathic helix (an N-BAR) can drive membrane curvature. These N-BAR domains are found in amphiphysin, endophilin, BRAP and Nadrin. BAR domains are also frequently found alongside domains that determine lipid specificity, like Pfam:PF00169 and Pfam:PF00787 domains in beta centaurins and sorting nexins respectively.
