Sodium channel subunit beta-2 UniProtKBInterproStringInteractive Modelling

215 aa; Sequence (Fasta) Identical sequences: Homo sapiens: Q5U0K8; Nomascus leucogenys: A0A2I3HIW5

Sequence Features

 55Interchain; with alpha subunit.
 28R -> Q (in ATFB14; the mutant results in reduced sodium currents and altered channel gating when coexpressed with SCN5A in a heterologous expression system; dbSNP:rs72544145). VAR_070229 dbSNP
 28R -> W (in ATFB14; the mutant results in reduced sodium currents and altered channel gating when coexpressed with SCN5A in a heterologous expression system; dbSNP:rs17121819). VAR_029131 dbSNP
 47R -> H (in dbSNP:rs17121818). VAR_029132 dbSNP
 211D -> G (found in a patient with Brugada syndrome; unknown pathological significance; induces a reduction in sodium current density most likely by decreasing SCN5A protein cell surface expression; dbSNP:rs587777023). VAR_070230 dbSNP
 160-180Helical.
 50-127
 34-147Immunoglobulin V-set domain
