Summary

MOB4 (MOB family member 4, phocein, HGNC:17261) is a protein-coding gene on chromosome 2q33.1, encoding MOB-like protein phocein (Q9Y3A3). Part of the striatin-interacting phosphatase and kinase (STRIPAK) complexes. It is a selective cancer dependency (DepMap: 57.1% of cell lines).

This gene was identified based on its similarity with the mouse counterpart. Studies of the mouse counterpart suggest that the expression of this gene may be regulated during oocyte maturation and preimplantation following zygotic gene activation. Alternatively spliced transcript variants encoding distinct isoforms have been observed. Naturally occurring read-through transcription occurs between this locus and the neighboring locus HSPE1.

Literature-anchored findings (GeneRIF, showing 4)

  • phosphorylation of MOB1 at Thr74 by MST2 is essential to make a complex of MOB1, MST2 and NDR1, and to fully activate NDR1 (PMID:18362890)
  • hMOB3 modulates MST1 apoptotic signaling and supports tumor growth in glioblastoma multiforme. (PMID:24872389)
  • Because of divergent evolution of key interface residues, MST4 and MOB4 could disrupt assembly of the MST1-MOB1 complex through alternative pairing and thereby increased YAP activity. Collectively, these findings identify the MST4-MOB4 complex as a noncanonical regulator of the Hippo-YAP pathway with an oncogenic role in PC (PMID:30072378)
  • Mob4 is essential for spermatogenesis in Drosophila melanogaster. (PMID:37259670)

Function. 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. Binds STRN4. Interacts with DNM1 and EPS15. Interacts with nucleoside diphosphate kinase. Interacts with CTTNBP2. Interacts with CTTNBP2NL. 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.

Subcellular location. Cytoplasm. Perinuclear region. Membrane. Golgi apparatus. Golgi stack membrane.

Post-translational modifications. Phosphorylated on serine residues.

Similarity. Belongs to the MOB1/phocein family.
