Krev interaction trapped protein 1 or Cerebral cavernous malformations 1 protein is a protein that in humans is encoded by the KRIT1 gene. This gene contains 16 coding exons and is located on chromosome 7q21.2. Loss of function mutations in KRIT1 result in the onset of cerebral cavernous malformation. Cerebral cavernous malformations (CCMs) are vascular malformations in the brain and spinal cord made of dilated capillary vessels.

Interactions

The KRIT1 protein, is 736 amino acids in length and has a variety of functions. KRIT1 has been shown to interact with multiple signaling pathways including; ITGB1BP1., reactive oxygen species, cell death, and angiogenesis. Related to cerebral cavernous malformations, this protein is required for maintaining the structural integrity of the vasculature.
