-
The Rs 1,900 test uses a cheek swab to examine a gene called actinin alpha-3 (ACTN3), which makes a protein that regulates energy release in muscles.

-
Thin filaments in muscle sarcomeres are anchored at the Z-disk by the cross-linking protein α-actinin (gold) and are capped by CapZ (pink squares).
-
It turns out that invertebrates only have one kind of α-actinin, and vertebrates made their suite of four in the process of a pair of whole genome duplications.
-
The α-actinin proteins are evolutionarily interesting.
-
Before duplication the ancestral sarcomeric α-actinin had the functions of both ACTN2 and ACTN3 in terms of tissue expression and functional isoforms.
-
The α-actinin proteins are the subtle orange lines in the Z disks on the left and right.
-
Using sarcomeric α-actinin as an example, after duplication of a gene capable of multiple interactions/functions, there are two possible distinct scenarios besides gene loss.
