Background: LRRC52

LRRC52 (Leucine-rich repeat-containing protein 52) belongs to an extracellular leucine-rich-repeat–only (Elron) cluster, which includes five other LRRC proteins: LRRC26, LRRC38, LRRC55, LRTM1 and LRTM2 (1). Elron cluster members are type I transmembrane proteins with an extracellular domain (ECD) containing several LRR motifs and a cytoplasmic C-terminal tail with a short stretch of acidic residues (1). The mature ECD of LRRC52 is 221 amino acids (aa), containing 5 LRR motifs, and shares 76% and 78% identity with mouse and rat LRRC52, respectively. LRRC-52 is dominantly expressed in testis and skeletal muscle and is also detected in several other tissues including placenta, kidney, lung, and some glands (2, 3). LRRC52 has been identified as a testes specific SLO3 K+ channel accessory protein in mouse (2). LRRC52 is proposed to be essential for alkalization dependent activation of the KSper current at physiological membrane potentials and pH (2). Activation of the SLO3 channel is critical in the fertilization process and loss of function results in infertility (2, 4, 5). A second Elron cluster protein, LRRC26, was recently identified as a regulatory subunit of SLO1 BK-type K+ channels, suggesting a general function for the entire family (6). Based on function, LRRC52 might be a therapeutic target for male contraception (7).
