1 A Per-Arnt-Sim (PAS) domain in the cytoplasmic N-terminal region of hERG regulates slow deactivation by making a direct interaction with another part of the hERG channel. Aminosalicylic Acid ETS transcription factor ERG Homo sapiens
2 A Per-Arnt-Sim (PAS) domain in the cytoplasmic N-terminal region of hERG regulates slow deactivation by making a direct interaction with another part of the hERG channel. Aminosalicylic Acid ETS transcription factor ERG Homo sapiens
3 We report that hERG channels with deletions of the cyclic nucleotide-binding domain (CNBD) had accelerated deactivation kinetics that were similar to those seen in hERG channels lacking the PAS domain. Aminosalicylic Acid ETS transcription factor ERG Homo sapiens
4 Together, these data suggest that the mechanism for regulation of slow deactivation in hERG channels is an interaction between the N-terminal PAS domain and the C-terminal CNBD. Aminosalicylic Acid ETS transcription factor ERG Homo sapiens
