The Kell protein is very similar to HAIR. That’s why I like to call it the #KellKurl. It is a protein strand that is extensively cross-linked with disulfide bonds which are formed from the oxidation of sulfhydryl groups (S—S) on cysteine residues. The Kell protein has 15 cysteine residues that crosslink and form a Kurl-like structure.
