Fyn

Fyn is a type of enzyme called a tyrosine kinase that plays a key role in cell signaling, helping cells respond to various stimuli. It is involved in regulating processes like cell growth, division, and movement. Fyn is especially important in the nervous system and immune responses. When signals from outside the cell are received, Fyn helps transmit those signals internally, activating other proteins to carry out specific functions. Proper Fyn activity is crucial for normal cell function; abnormalities can contribute to diseases such as cancer or neurological disorders.
