The cytoplasmic tail of CD44 is required for basolateral localization in epithelial MDCK cells but does not mediate association with the detergent-insoluble cytoskeleton of fibroblasts
A number of recent reports on the trafficking of receptor proteins in MDCK epithelial cells have provided evidence that delivery to the basolateral domain requires a specific targeting sequence and that deletion of this sequence results in constitutive expression on the apical surface. To date, these studies have concentrated on receptors which are competent for internalization via the clathrin...
متن کاملTransmembrane domain of CD44 is required for its detergent insolubility in fibroblasts.
The hyaluronan receptor CD44 is an abundant glycoprotein expressed on a variety of different cell types. In fibroblasts a significant portion of receptor molecules remain in the detergent-insoluble fraction after Triton X-100 extraction. Detergent insolubility of these CD44 molecules has been interpreted to reflect their association with the cytoskeleton. In this study we examined the structura...
متن کاملThe Cytoplasmic Domain of the Ligand EphrinB2 Is Required for Vascular Morphogenesis but Not Cranial Neural Crest Migration
The transmembrane ligand ephrinB2 and its cognate Eph receptor tyrosine kinases are important regulators of vascular morphogenesis. EphrinB2 may have an active signaling role, resulting in bi-directional signal transduction downstream of both ephrinB2 and Eph receptors. To separate the ligand and receptor-like functions of ephrinB2 in mice, we replaced the endogenous gene by cDNAs encoding eith...

phase domains, leaving the lo-phase domains relatively unchanged as DRMs. Both of these approaches showed that TX100 did not substantially change the relative amounts of membrane in the two phases. By contrast, using calorimetry, Heerklotz and colleagues reported that TX100 can induce phase separation in previously uniform mixtures (45, 46). However, results of the other two studies described a...
