UniProt data
UniProt name: LRC52_HUMAN (Q8N7C0)
Gene name: LRRC52
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. KCNU1 channel auxiliary protein. May modulate KCNU1 gating properties. {ECO:0000269|PubMed:22547800, ECO:0000269|PubMed:23129643}.
Subcellular location: Cell membrane {ECO:0000250}; Single-pass membrane protein {ECO:0000250}. Note=Expression at the cell surface may require the presence of KCNU1.
Transmembrane domains:
- 245-265, 21 AA, Helical. {ECO:0000255}.
Sequence: 313 AA
