Hepatitis B virus X-interacting protein is a protein that in humans is encoded by the HBXIP gene.^[1][2]

This gene encodes a protein that specifically complexes with the C-terminus of hepatitis B virus X protein (HBx). The function of this protein is to negatively regulate HBx activity and thus to alter the replication life cycle of the virus.^[2]

Interactions

HBXIP has been shown to interact with NCOA6.^[3]
