<p><b>New page</b></p><div>'''Fototropini''' so fotoreceptorske beljakovine (najpogosteje so to flavoproteini), ki posredujejo fototropski odziv pri višjih rastlinah. Skupaj s kriptokromi in fitokromi omogočajo rastlini, da se odzove in spremeni svojo rast v smeri, glede na količino svetlobe v okolju. Fototropini so pomembni tudi za odpiranje in zapiranje listnih rež.<br />
<br />
Fototropini so del fototropskega senzoričnega sistema, v obratih, ki povzročajo različne odzive na okolje v rastlinah. Pomembni so za premike kloroplastov znotraj same celice saj s tem zagotavljajo rastlini večje količine hrane ter močnejšo in hitrejšo rast.<br />
<br />
Fototropini so avtofosforske proteinske kinaze, ki se odzivajo in dajejo odgovor rastline na modro svetlobo. Preden postanejo kriptokromi in fitokromi v celici aktivni, fototropini zaznajo modro svetlobo ter celici posredujejo zahtevo za prepis mRNA. Ko se mRNA prepiše se v celični membrani fototropinska beljakovina razvije in povzroči fosforizacijo. Fosforizacija sproži verižne dogodke znotraj celice tako, da postanejo kriptokromi in fitokromi aktivni in rastlino obrnejo proti povečani količini svetlobe.<br />
