Humans and cows have almost identical DNA instructions for making a protein called calcineurin B — their blueprints match 97.1% in that section, which means it's super similar between the two species.

Isolation and characterization of a cDNA clone coding for the calcium-binding subunit of calcineurin from bovine brain: an identical amino acid sequence to the human protein.

Cross-Sectional Study

1994

The study found that the gene for calcineurin B in cows is almost exactly the same as in humans, with 97.1% similarity in the protein-coding part — just like the claim says.

Similar Assertions

The brain protein calcineurin B in cows is exactly the same as the one in humans — letter for letter in its building blocks — which means it’s likely worked the same way for millions of years and could be studied across species.
