HUS1B: Proteins and Enzymes

HUS1B is encoded by the Hus1B gene is most closely related to HUS1, a component of a cell cycle checkpoint protein complex involved in cell cycle arrest in response to DNA damage. This protein can interact with the checkpoint protein RAD1 but not with RAD9. Over expression of this protein has been shown to induce cell death, which suggests a related but distinct role of this protein, as compared to HUS1. Hus1B is expressed strongly in testis, less in spleen, thymus, prostate, colon and leukocytes.
