    basic FUNCTION
  • intracellular relay integrating diverse regulatory signals of the cell's environment for regulation of cell proliferation and differentiation
  • able to depolymerize interphase microtubules when overexpressed
  • inhibits apoptosis by acting through a mitochondrial apoptotic pathway
  • regulation of the microtubule filament system by destabilizing microtubules
  • could play a role in regulation of the growth of osteoblast-like cells in response to various hormonal stimuli
  • required for the induction of long-term potentiation in afferent inputs to the amygdala and is essential in regulating both innate and learned fear
  • critical molecular component linking the basolateral complex of the amygdala nuclei-associated neural circuitry with innate parental behaviors and adult social interactions
  • microtubule-destabilizing protein, that promotes microtubule depolymerization by increasing the microtubule catastrophe rate (Wen 2010)
  • possibly a pathogenic factor in SMA, and the disruption of microtubule maintenance may be partly involved in SMA pathogenesis (Wen 2010)
  • is a regulator of the microtubule network during T cell activation
  • role of stathmin in microtubule-dependent control of endothelial permeability
  • regulates mitotic entry, partially via MTs, to control localization and activation of both AURKA and PLK1
  • has a dual function as both an oncogene and a metastasis suppressor
  • might play its oncogenic role by an interaction with NfKB1 pathway
  • stathmin controls likely the transition from neuronal precursors to early postmitotic neurons
  • performs a critical function in cell proliferation by regulating microtubule polymerization
  • mediates hepatocyte resistance to death from oxidative stress by down regulating MAPK8 and maintaining mitochondrial integrity
  • major microtubule-depolymerizing protein, involved in cell cycle progression and cell motility
  • may have an important role in in non-small cell lung cancer (NSCLC) progression and could serve as a potential prognostic marker for patients with NSCLC
  • SEPTIN2-mediated cytoskeletal rearrangement and STMN1-mediated differentiation may contribute to changes in cell morphology and differentiation of Hodgkin and Reed-Sternberg (H/RS) cells with CD99 upregulation in Hodgkin lymphoma (HL)
  • pivotal inhibitory role for stathmin in classically activated macrophages
  • CELLULAR PROCESS cell cycle, checkpoint
    cell life, proliferation/growth
  • G2/M transition
  • mitotic spindle organization and biogenesis
    signaling signal transduction
    a component
  • many different phosphorylated forms observed, depending on specific combinations among the sites which can be phosphorylated
  • MAPK is responsible for the phosphorylation of stathmin in response to NGF
  • required for the induction of long-term potentiation in afferent inputs to the amygdala
  • being essential in regulating both innate and learned fear
    small molecule
  • KIST
  • two alpha/beta-tubulin heterodimers
  • cyclin-dependent kinase inhibitor 1B (p27, Kip1)
  • heat shock 70kDa protein 5 (glucose-regulated protein, 78kDa)
  • U2AF homology motif (UHM) kinase 1
  • RB1-inducible coiled-cool 1
  • tumor susceptibility gene 101
  • iInteraction between PTP4A3 and stathmin leads to microtubules destabilization of colorectal cancer (CRC) cells, which contributes to progression and metastasis of CRC
  • interacting with SIVA1 (inhibits STMN1 activity directly as well as indirectly, and via the inhibition of STMN1, SIVA1 enhances the formation of microtubules and impedes focal adhesion assembly, cell migration, and EMT)
  • downregulated by PDEF, suggesting that PDEF may inhibit prostate cancer progression by transcriptional downregulation of oncogenic STMN1 expression
  • STMN1 is a relevant CDKN1B binding partner (cooperates with CDKN1B to control the early phase of G1 to S phase transition and this function may be of particular relevance in the context of tumor progression)
  • cell & other
    induced by phosphorylation induced by multiple signal transduction pathways
  • both activation and repression by NF-Y
  • NF-Yis a major transcription factor promoting expression of STMN1

    Variant & Polymorphism
    Candidate gene
  • SIVA1 and STMN1 may be biomarkers for breast cancer
  • could serve as a potential prognostic marker for patients with in non-small cell lung cancer (NSCLC)
  • Therapy target
    SIVA1 and STMN1 may be therapeutic targets for breast cancer
    neuromuscularlaterale amyotrophy sclerosis 
    inhibition of stathmin expression in SMA diminished the SMA phenotype, these results suggest that microtubule dynamics may be a potential therapeutic target and could provide a novel avenue for SMA therapy
    modulation of LRRC4 or STMN1 expression may be useful for design of new therapies for the intervention of glioma
  • deficiency in fear processing in stathmin(-/-) female mice leads to improper threat assessment and profound deficiency is observed in maternal behavior as well
