TGN38/41 cycles between the trans-Golgi network (TGN) and plasma membrane, traversing three sorting compartments: the TGN, plasma membrane and early endosome. The targeting signals responsible for this complex itinerary reside in a short cytoplasmic domain of 33 amino acid residues. We show that phosphorylation of the cytoplasmic domain of TGN38 prevents binding of p62--a cytoplasmic protein essential for exocytic vesicle formation.

cDNA clones for the X-linked PGK-1 were obtained from a tammar wallaby liver by PCR and sequenced. The PGK-1 gene published here is the consensus sequence of those clones. The sequence represents an open reading frame of 1251 bp.

Such Tc cells can lyse TNP-specific B cells activated with TNP-KLH, but not with TNP-ovalbumin. Cytotoxicity was inhibited by anti-H-2K/D antibodies, but not by anti-Ia antibodies, suggesting a major histocompatibility complex class I-restricted killing.
