MIEN1
Function
Increases cell migration by inducing filopodia formation at the leading edge of migrating cells. Plays a role in regulation of apoptosis, possibly through control of CASP3. May be involved in a redox-related process.
Post-translational modifications
Isoprenylation facilitates association with the plasma membrane and enhances the migratory phenotype of cells by inducing increased filopodia formation.
Sequence Similarities
Belongs to the SelWTH family.
Tissue Specificity
Among normal tissues, present only in Leydig cells. Strongly up-regulated in breast cancers and in brain cancer distant metastasis (at protein level). Up-regulated in prostate cancer cells and in the higher grades of prostate adenocarcinoma (at protein level).
Cellular localization
- Cytoplasm
- Cytosol
- Cell membrane
- Lipid-anchor
- Cytoplasmic side
- Concentrates at the leading edge of migrating cells. Localizes outside membrane raft regions.
