Krev interaction trapped protein 1 is a protein that in humans is encoded by the CCM1 gene.[1][2][3] This gene contains 16 coding exons and is located on chromosome 7q21.2. Loss of function mutations in CCM1 result in the onset of Cerebral cavernous malformation.[4] Cerebral cavernous malformations (CCMs) are vascular malformations in the brain and spinal cord made of dilated capillary vessels.

Interactions[edit]

The normal CCM1 protein, KRIT1 (Krev Interaction Trapped), is 736 amino acids in length and has a variety of functions. KRIT1 has been shown to interact with multiple signaling pathways including; ITGB1BP1.,[5][6] reactive oxygen species,[7] cell death,[8] and angiogenesis.[9] Related to the CCM illness, this protein is required for maintaining the structural integrity of the vasculature.[10][11]
