CASK (Calcium/calmodulin-dependent serine protein kinase gene)
Calcium/calmodulin-dependent serine protein kinase (CASK) is a protein that helps tissues grow and communicate between cells. In muscles, it helps make connections between nerves and muscles. When pigeons race, it causes continuous changes in their muscles. In most pigeon species including rock pigeons, we see the normal wild-type CASKGG. In racing pigeons, a CASKA mutation was found that can be associated with a functional change. Racing pigeons with this CASKA mutation are said to have better flight ability. A double mutation CASKAA is very interesting for breeding pigeons.
Feathers
- 4-5 freshly plucked breast feathers
- Fallen moulting feathers, down feathers and blood feathers should be avoided. These contain insufficient DNA or can cause damage to the feather follicle when pulled out. Blood feathers are the new feathers that can be recognised by the blue sleeve at the base of the feather.
- To avoid contamination, the calamus (the end of the feather that comes out of the bird's skin) must not be touched with the hands
Blood sample
- A small amount (capillary tube) is sufficient for accurate analysis
Cheek swab of a nestling
- A gentle way to collect DNA from young birds
- Caution: avoid mixing with food or food waste
- Turnaround time
- You will receive an email when your results and certificate are available on your personal portal
