Receptor-mediated endocytosis of albumin by the renal proximal tubule requires a number of proteins including megalin/cubilin, sodium/hydrogen exchanger isoform 3 (NHE3) and ClC-5, as well as the PSD-95/Dlg/Zo-1 (PDZ) scaffold sodium/hydrogen exchanger regulatory factor 2 (NHERF2). Despite members from the AGC kinase family, v-Akt Murine Thymoma Viral Oncogene (Akt or Protein Kinase B) and Serum/Glucocorticoid regulated Kinase 1 (Sgk-1) regulating a number of essential proteins in the albumin handling pathway, their role in uptake is largely unknown.
