PIK3CB

该基因编码磷酸肌醇3激酶（pi3k）催化亚单位的一个亚型。这些激酶在涉及真核细胞外膜受体的信号传导途径中起重要作用，并以其催化亚单位命名。编码蛋白是pi3kba（pi3kb）的催化亚基。pi3kb是中性粒细胞活化途径的一部分，中性粒细胞在损伤或感染部位与免疫复合物结合。选择性剪接导致多个转录变体。[由RefSeq提供，2011年12月]
This gene encodes an isoform of the catalytic subunit of phosphoinositide 3-kinase (PI3K). These kinases are important in signaling pathways involving receptors on the outer membrane of eukaryotic cells and are named for their catalytic subunit. The encoded protein is the catalytic subunit for PI3Kbeta (PI3KB). PI3KB has been shown to be part of the activation pathway in neutrophils which have bound immune complexes at sites of injury or infection. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2011]
