Mechanistic narrative

Synthesis pass · prose summary of the discoveries below

KNSTRN (SKAP/kinastrin) is a microtubule plus-end tracking protein and kinetochore component that, as the major astrin partner, governs the stability and force-responsiveness of kinetochore-microtubule attachments during mitosis (PMID:21402792, PMID:20937697). It assembles into a reconstituted four-subunit Astrin-SKAP complex containing DYNLL1/LC8 and MYCBP, and this complex binds microtubules synergistically with the Ndc80 complex through a microtubule-binding domain that is distinct and separable from its EB1-dependent SXIP plus-tip-tracking module (PMID:28841134, PMID:27095104, PMID:20937697). The complex localizes preferentially to bioriented, tension-bearing kinetochores, a restriction imposed by Aurora B, and is recruited there through interaction with MIS13 of the KMN network and cooperation with CENP-E (PMID:20937697, PMID:23035123, PMID:22110139). Rather than acting as a static clamp, Astrin-SKAP reduces friction at the kinetochore-microtubule interface, acting as a lubricant that coordinates sister-kinetochore movement, dissipates force, and prevents detachment under load; this depends directly on SKAP's microtubule binding (PMID:35580605, PMID:40154475). KNSTRN function is tuned by post-translational modification: GSK3β phosphorylation directs SKAP binding to the Kif2b depolymerase, while Src-family phosphorylation of Tyr-87 impairs microtubule binding (PMID:27982129, PMID:33510346). Beyond mitosis, KNSTRN supports EGF-directed and T-cell migration via IQGAP1 and MAP4, modulates UV-induced apoptosis through Prp19, and in cancer activates AKT signaling by competing with PTEN at the plasma membrane (PMID:26242911, PMID:29180244, PMID:24718257, PMID:33452459). Cancer-associated mutation (p.Ser24Phe) disrupts sister chromatid cohesion and promotes aneuploidy, and loss-of-expression underlies the cellular defects of Roifman-Chitayat syndrome (PMID:25194279, PMID:29180244).

2016 SKAP is expressed as two distinct isoforms in mammals: a shorter mitotic isoform and a longer testis-specific isoform. Only the short mitotic isoform rescues SKAP depletion in mitosis and displays robust microtubule plus-end tracking including localization to astral microtubules. SKAP microtubule binding mutants that abolish plus-end tracking cause spindle positioning defects and reduce Clasp1 localization at microtubule plus ends, leading to increased lateral microtubule contacts with the cell cortex.

2016 KNSTRN (SKAP) contains a microtubule-binding domain distinct from the SXIP motif that mediates EB protein binding and plus-end tracking.

2022 KNSTRN (SKAP) physically interacts with Aurora B and spontaneously phase-separates in vitro via weak multivalent interactions into droplets. SKAP and Aurora B form heterogeneous coacervates in vitro that recapitulate in vivo SKAP comet dynamics.

2022 The Astrin-SKAP complex reduces friction at the kinetochore-microtubule interface. SKAP depletion dampens movement and decreases coordination of metaphase sister kinetochores, increases inter-kinetochore tension, and slows kinetochore movement on both polymerizing and depolymerizing microtubules.
