Summary

STRIP1 (striatin interacting protein 1, HGNC:25916) is a protein-coding gene on chromosome 1p13.3, encoding Striatin-interacting protein 1 (Q5VSL9). Plays a role in the regulation of cell morphology and cytoskeletal organization. It is a selective cancer dependency (DepMap: 36.1% of cell lines).

This gene encodes a member of the striatin-interacting phosphatase and kinase complex, which is involved in localization of the Golgi body. The encoded protein participates in cytosketelal organization. Alternative splicing results in multiple transcript variants.

  • this study propose that the STRIPAK complex, FAM40A, FAM40B and STRN3, regulates the mode of cancer cell migration by controlling the activity of MST3 and 4, which locally coordinate the phosphorylation of ERM proteins and inhibit the dephosphorylation of MLC leading to increased actin-membrane linkage. (PMID:25531779)
  • STRIP1 is required for mesenchymal cell migration and is enriched in cellular protrusions in mesenchymal migrating cells. (PMID:29203676)
  • These results demonstrate the importance of the FAM40 proteins for endothelial cell physiology, and suggest that they act as part of the CCM3-containing STRIPAK complex. (PMID:30509168)

Function. Plays a role in the regulation of cell morphology and cytoskeletal organization. Required in the cortical actin filament dynamics and cell shape. Part of the striatin-interacting phosphatase and kinase (STRIPAK) complexes. STRIPAK complexes have critical roles in protein (de)phosphorylation and are regulators of multiple signaling pathways including Hippo, MAPK, nuclear receptor and cytoskeleton remodeling. Different types of STRIPAK complexes are involved in a variety of biological processes such as cell growth, differentiation, apoptosis, metabolism and immune regulation.

Subunit / interactions. Part of the core of STRIPAK complexes composed of PP2A catalytic and scaffolding subunits, the striatins (PP2A regulatory subunits), the striatin-associated proteins MOB4, STRIP1 and STRIP2, PDCD10 and members of the STE20 kinases, such as STK24 and STK26. The STRIPAK complex can be extended by adapter proteins such as SLMAP:SIKE1, CTTNBP2 or CTTNBP2NL. Interacts with CDC42BPB. Interacts with CTTNBP2NL.
