SBP2 – Protein-Protein Interactions

Truncated version of SBP1, the fragment of the angiotensin-converting enzyme 2 (ACE2) peptidase domain (PD) alpha1 helix important for the interaction of ACE2 with the severe acute respiratory syndrome (SARS coronavirus receptor binding domain (SARS-CoV-2-RBD). Unlike SBP1, SBP2 does not associate with the spike RBD protein.
