    ..It is also ubiquitously expressed in tissues and in ZR-75-1 breast cancer cells and LNCaP prostate carcinoma cells as a smaller variant generated by splicing out of an exon encoding 22 amino acids in the hinge region of the protein. ..

    ..Our results suggest that Clint might participate in the formation of clathrin-coated vesicles at the level of the trans-Golgi network and remains associated with the vesicles longer than clathrin and adaptors. ..

    ..Hence, Tat enters T cells essentially like diphtheria toxin, using clathrin-mediated endocytosis before low-pH-induced and Hsp90-assisted endosomal translocation. Cell responses are then induced from the cytosol. ..
