21. Leucine potently activates the mammalian target of rapamycin kinase that regulates cell growth.22. The encoded protein contains 17 leucine -rich repeats and one PDZ domain. 23. This kinase contains a SH3 domain and a leucine zipper-basic motif. 24. TSC22D1 forms homodimers via its conserved leucine zipper domain and heterodimerizes with TSC22D4. 25. A Leucine zipper pattern was found beginning at Lys113 and ending at Lys134. 26. The first two references listed would provide further basic information regarding leucine zippers. 27. Casein hydrolysate CH or mixtures of leucine and lysine can also be used. 28. It is believed that this is achieved by limiting the essential amino acid leucine . 29. CREB proteins are activated by phosphorylation from various kinases, including leucine zipper motif. 30. Leucine -rich repeats are frequently involved in the formation of protein protein interactions.
