Complement component 1 Q subcomponent-binding protein, mitochondrial is a protein that in humans is encoded by the C1QBP gene.[1][2][3]

The human complement subcomponent C1q associates with C1r and C1s in order to yield the first component of the serum complement system. The protein encoded by this gene is known to bind to the globular heads of C1q molecules and inhibit C1 activation. This protein has also been identified as the p32 subunit of pre-mRNA splicing factor SF2, as well as a hyaluronic acid-binding protein.[3]

Interactions

C1QBP has been shown to interact with Protein kinase D1,[4] BAT2,[5] PRKCD,[4] PKC alpha[4] and Protein kinase Mζ.[4]
