Elevated transglutaminase activity and formation of cornified envelopes are markers of terminal differentiation in mouse epidermal cells. Epidermal transglutaminase catalyzes cornified envelope formation and in cultured cells is inducible by calcium ion or phorbol ester tumor promoters. Retinoic acid also induces transglutaminase activity but inhibits cross-linked envelope formation. This appar...

We developed a method using a single set of degenerate oligonucleotide primers for amplification of the conserved active site of transglutaminases by reverse transcription-polymerase chain reaction (RT-PCR) and identification of the PCR products by cleavage with diagnostic restriction enzymes. We demonstrate amplification of tissue transglutaminase (TGC), keratinocyte transglutaminase (TGK), pr...

Osteopontin is a multifunctional glycoprotein with roles in immunomodulation, inflammatory response, tissue mineralization, and tissue remodeling, which are mediated primarily through integrins. Transglutaminase 2 selectively cross-links proteins by isopeptide bonding. Osteopontin is one of the substrates of this enzyme and undergoes polymerization; however, the biological meaning of this polym...
