Secondry Information

Protein Function conglutinin in the serum of dairy cows depends on many factors such as breeding, the season of the year, the stage of the reproductive cycle and infection
Biochemical Properties Conglutinin contain 4 trimeric units; there are 7 cysteine residues present which are capable of forming inter – and/or intramolecular disulfide bridges; The collagen- like region of conglutinin contains eight hydroxylysine residues, which are possible glycosylation sites; conglutinin molecules adhere to each other in the central lob region, forming rosette-like aggregates
Significance in milk effector molecules in innate immunity; . Conglutinin does not appear in the serum of calves until after it has received colostrum; then its concentration gradually increases up to the 80th week of life, when it reaches the level characteristic for adult cattle
PTMs presence of O-linked glycans of β(1-3)-GalNAc and α-(2-3) linked sialic acid type. No N-linked glycans were detected
