Krev interaction trapped protein 1 or Cerebral cavernous malformations 1 protein is a protein that in humans is encoded by the KRIT1 gene.[4][5][6][7] 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.[8] 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.,[9][10] reactive oxygen species,[11] cell death,[12] and angiogenesis.[13] Related to cerebral cavernous malformations, this protein is required for maintaining the structural integrity of the vasculature.[14][15]
