Fig 4. Lama glama complete CSN3 cDNA (κ-casein).

Complete cDNA sequence (EMBL acc. no.: LK999995) and exon subdivision (brackets) of L. glama CSN3 (upper line) and comparative alignment with the homologous κ-casein cDNA of C. dromedarius (EMBL acc. no.: Y10082). Dashes represent identical nucleotides to those in upper lines. In lower cases the 5’- and 3’- Un-Translated Regions (UTR), the polyadenylation signal (Pas) is indicated by a box. The corresponding mature protein is reported in bold. The chymosin cleavage site (Phe⁹⁷-Ile⁹⁸) is indicated by a flash-arrow, whereas the glycomacropeptide (GMP) 65 amino acids long is reported in bold italics. The signal peptide is in italics and asterisk represents the termination stop codon. P, phosphorylated serine, whereas the plusses indicate Ser preferentially phosphorylated by Fam20C; G, glycosylated threonines.
