Secondary Information

Protein Function involved in cytoskeletal focal adhesion dynamics.Increases cell migration by inducing filopodia formation.Also considered an oncogenic protein, because MIEN1 overexpression functionally enhances migration and invasion of tumor cells via modulating the activity of AKT.
Biochemical Properties MIEN1 protein contains a consensus sequence for prenylation comprising the last 4 amino acids, CVIL, at the C terminus, a CAAX motif predicted to be post-translationally modified by protein geranylgeranyltransferase-1.It contains a central α/β core domain consisting of a mixed parallel/anti-parallel four-stranded β-sheet with two distorted α-helices.

Significance of PTMs contains a consensus sequence for prenylation comprising the last 4 amino acids.Geranylation of MIEN1 at the CAAX motif facilitated the association of the protein to the inner leaflet of plasma membrane, enhancing the migratory phenotype of cells by inducing increased filopodia formation and potentiating directional migration.-CAAX- motif in the C terminal is predicted to be post-translationally modified by protein geranylgeranyltransferase-1.
