Abstract
Two homologous peptides, designated thymosin beta 4 and thymosin beta 10, respectively, have been shown to be widely distributed in mammalian cells and tissues (S. Erickson-Viitanen, S. Ruggieri, P. Natalini, and B.L. Horecker (1983) Arch. Biochem. Biophys. 221, 570-576; S. Erickson-Viitanen, S. Ruggieri, P. Natalini, and B.L. Horecker, (1983) Arch. Biochem. Biophys. 225, 407-413). In the rabbit, thymosin beta 4 is replaced by a variant, thymosin beta ala4, that contains alanine in place of serine at the blocked NH2-terminus. It is reported that in rabbit tissues thymosin beta 10 is also replaced by a variant, designated thymosin beta arg10, that contains an additional amino acid, arginine, inserted following lysine-38. The rabbit tissues analyzed also differ from those of other mammals in the relative quantities of thymosin beta ala4 and beta arg10, which are nearly equal, compared to tissues from other mammals where the quantities of thymosin beta 10 are only one-third to one-tenth those of thymosin beta 4.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
