DPP6 Domains Responsible for Its Localization and Function

DPP6 domains responsible for its localization and function.

Dipeptidyl peptidase-like protein 6 (DPP6) is an auxiliary subunit of the Kv4 family of voltage-gated K(+) channels known to enhance channel surface expression and potently accelerate their kinetics. DPP6 is a single transmembrane protein, which is structurally remarkable for its large extracellular domain. Included in this domain is a cysteine-rich motif, the function of which is unknown.

Distinct LIN-10 domains are required for its neuronal function, its epithelial function, and its synaptic localization.

alpha-Amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA)-type glutamate receptors (AMPARs) mediate excitatory neurotransmission at neuronal synapses, and their regulated localization plays a role in synaptic plasticity. In Caenorhabditis elegans, the PDZ and PTB domain-containing protein LIN-10 is required both for the synaptic localization of the AMPAR subunit GLR-1 and for vulval fate...

DPP6 Localization in Brain Supports Function as a Kv4 Channel Associated Protein

The gene encoding the dipeptidyl peptidase-like protein DPP6 (also known as DPPX) has been associated with human neural disease. However, until recently no function had been found for this protein. It has been proposed that DPP6 is an auxiliary subunit of neuronal Kv4 K(+) channels, the ion channels responsible for the somato-dendritic A-type K(+) current, an ionic current with crucial roles in...
