Figure(s):Figure 2
Annotation description:Figure 2: in biochemical fractions prepared from mice forebrain, Slack (KCTN1) was enriched in PSD fractions. Staining was abolished in Slack knockout mice.

Figure 2, 3: Infant Slack-/- show reduced NMDAR-mediated transmission and lack mGluR LTD.

Figure 4: Slack-/- deficiency impairs dephosphorylation of GluA1 S845 after LTD induction.

Figure 5: NMDAR-dependent LTD but not LTP is impaired in adult Slack-/-.

Based on the known transmembrane topology of this protein, "integral component of ... membrane" term was selected.

Additional literature:"Combined, our findings suggest that Slack-dependent K+ signals oppose the NMDAR-mediated excitotoxic neuronal injury by promoting pro-survival signaling via the BDNF/TrkB and Erk axis." @ PMID:33817875

The sodium-activated potassium channels Slick (Slo2.1, KCNT2) and Slack (Slo2.2, KCNT1) are paralogous channels of the Slo family of high-conductance potassium channels.

- Slick and Slack channels co-localize in the same cellular compartment.
- Slick and Slack channels assemble into cellular protein complexes in mouse brain.
- potential interaction partners include TMEM293, SNCB, DPP10, DLG3 @ PMID:29124216

"Our findings suggest that Slack channels regulate synaptic transmission within the spinal cord dorsal horn and by doing so establishes the threshold for thermal nociception." @ PMID:28604221
