UniProt data
UniProt name: LRC38_HUMAN (Q5VT99)
Gene name: LRRC38
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 type I membrane protein {ECO:0000250}.
Transmembrane domains:
- 250-270, 21 AA, Helical. {ECO:0000255}.
Sequence: 294 AA
