FcRH5 is a surface protein found almost only on B cells and myeloma plasma cells, which makes it a target for T-cell engaging antibodies in multiple myeloma. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

A type I transmembrane protein with immunoglobulin-like domains that modulates B-cell receptor signalling; its restricted lineage expression, like BCMA and GPRC5D, is what makes it a T-cell redirection target.

Where it is found
  • Multiple myeloma (near-universal on plasma cells)
  • B-cell lymphomas and chronic lymphocytic leukaemia
