– Component of the MICOS complex, a large protein complex of the mitochondrial inner membrane that plays crucial roles in the maintenance of crista junctions, inner membrane architecture, and formation of contact sites to the outer membrane. Plays an important role in the maintenance of the MICOS complex stability and the mitochondrial cristae morphology. Mitofilin Protein, Rat, Recombinant (His) is expressed in E. coli expression system with N-10xHis tag. The predicted molecular weight is 66.3 kDa and the accession number is Q3KR86.
