Day 39 (2p12-2p11.2): a cluster of regeneration genes

Screen Shot 2016-02-14 at 11.10.46 AM

Day 39 has only 11 protein-coding genes, but it has four of the five genes for regeneration proteins.  REG1A, for example, is a protein originally found by studying kidney stones. Pancreatic cells secrete REG1A as they are undergoing programmed cell death – it’s a signal to create more cells to replace them.

Click here to see your REG1A gene on Day 39. Notice that it is a very short coding sequence, and that it has two neighboring REG genes.
