multiple TASK currents were present in a DRG nociceptor and differentially contributed to distinct discharge mechanisms.
Title: Characterization and function of TWIK-related acid sensing K+ channels in a rat nociceptive cell.
TASK-1 mRNA is present in ventrolateral medulla neurons that regulate respiration or circulation (C1 adrenergic neurons). TASK channels are expressed by respiratory cells with putative rhythmogenic function and by premotor and motor neurons.
Title: Cardiorespiratory neurons of the rat ventrolateral medulla contain TASK-1 and TASK-3 channel mRNA.

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.
