LRRC 55(leucine-rich repeat-containing protein 55)蛋白是BK(Big conductance potassium channel)通道的一个辅助性γ亚基,在胞浆Ca ~(2+)缺乏的情况下,可使BK通道的GV发生50 mV左右的位移。LRRC 55蛋白也是BK通道中唯一在哺乳动物神经系统中表达的γ亚基。然而,LRRC 55基因在成年哺乳动物脑中的表达模式仍不清楚。本研究应用原位杂交技术研究了LRRC 55 mRNA在成年小鼠脑内的分布。我们发现LRRC 55 mRNA在成年小鼠内侧缰核(MHb)、小脑和脑桥中有丰富的表达。然而,LRRC 55在MHb和小脑中的潜在作用可能基于这些脑区域中BK通道的功能而不同。
LRRC55 (leucine-rich repeat-containing protein 55) protein is an auxiliary γ subunit of BK (Big conductance potassium channel) channels, which leftward shifts GVs of BK channels around 50 mV in the absence of cytosolic Ca2+. LRRC55 protein is also the only γ subunit of BK channels that is expressed in mammalian nervous system. However, the expression pattern of LRRC55 gene in adult mammalian brain remains elusive. In this study, we investigated the distribution of LRRC55 mRNA in the adult mouse brain by using in situ hybridization. We found that LRRC55 mRNA is richly expressed in the adult mouse medial habenula nucleus (MHb), cerebellum and pons. However, the potential role of LRRC55 in MHb and cerebellum could be different based on the function of BK channels in these brain regions.
