Abstract
Recent studies indicate that filtered albumin is retrieved in the proximal tubule (PT) via three pathways: receptor‐mediated endocytosis via cubilin (high affinity) and megalin (low affinity), and fluid‐phase uptake. Expression of megalin is required to maintain all three pathways, making it challenging to determine their respective contributions. Moreover, uptake of filtered molecules varies...
An exon representing a novel clathrin heavy chain gene (CLTCL) was isolated during gene identification studies and transcription mapping of human chromosome 22. Isolation and sequencing of cDNA clones corresponding to this exon revealed extensive similarity of the predicted amino acid sequence of this gene product to those of clathrin heavy chain genes of other species. Northern blot analysis has...
