Trafficking-dependent roles of the Kv3.1b potassium channel are dependent on N229 site-specific glycosylation and N-glycan structure, and operate through a mechanism whereby specific N-glycan structures regulate cell surface expression.
Title: Identification and characterization of site-specific N-glycosylation in the potassium channel Kv3.1b.
This study demonstrated that Kv3.1b potassium channel expression in motor cortex pyramidal cells.
Title: Expression of Kv3.1b potassium channel is widespread in macaque motor cortex pyramidal cells: A histological comparison between rat and macaque.
Our findings provide direct evidence that N-glycans of Kv3.1 splice variants contribute to the placement of these glycoproteins in the plasma membrane of neuronal-derived cells while those of Kv1.1 were absent.
Title: Complex N-Glycans Influence the Spatial Arrangement of Voltage Gated Potassium Channels in Membranes of Neuronal-Derived Cells.
Results indicate that Src kinase may play an important role in regulating membrane trafficking of Kv3.1b channels.
Title: Src regulates membrane trafficking of the Kv3.1b channel.
high-affinity multimeric binding between the Kv3.1 T1 domain and KIF5B requires three basic residues in the KIF5B tail. Kv3.1 T1 competes with the motor domain and microtubules, but not with kinesin light chain 1 (KLC1), for binding to the KIF5B tail.
Title: Activation of conventional kinesin motors in clusters by Shaw voltage-gated K+ channels.
The unique N-terminus of DPP6K modulates the effects of KChIP proteins, slowing recovery and producing a negative shift in the steady-state inactivation curve.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
