UniProt data
UniProt name: LRC55_HUMAN (Q6ZSA7)
Gene name: LRRC55
Organism: Homo sapiens (Human).
Function: Auxiliary protein of the large-conductance, voltage and calcium-activated potassium channel (BK alpha). Modulates gating properties by producing a marked shift in the BK channel's voltage dependence of activation in the hyperpolarizing direction, and in the absence of calcium. {ECO:0000269|PubMed:22547800}.
Subcellular location: Cell membrane {ECO:0000250}; Single-pass membrane protein {ECO:0000250}.
Transmembrane domains:
- 272-292, 21 AA, Helical. {ECO:0000255}.
Sequence: 311 AA
