背景说明：This peptide is a fragment of the human aquaporin-2 (AQP2) phosphorylated at Ser261. Protein phosphorylation plays a key role in vasopressin signaling in renal-collecting duct. Phosphorylation at several AQP2 residues including Ser256 and Ser261, is altered in response to vasopressin. It is possible that both sites are involved in vasopressin-dependent AQP2 trafficking. 该肽是在Ser261处磷酸化的人aquaporin-2（AQP2）的片段。 蛋白质磷酸化在肾脏集合管中的加压素信号传导中起关键作用。 响应于加压素，几个AQP2残基（包括Ser256和Ser261）的磷酸化被改变。 两个位点都可能参与依赖血管加压素的AQP2交易。
