STAT5

STAT5 is a protein that acts as a messenger inside cells, helping transmit signals from the outside to the inside. It is part of the JAK-STAT pathway, which responds to various growth factors and hormones. When activated, STAT5 attaches to specific DNA regions, turning on genes that influence cell growth, division, and survival. Proper functioning of STAT5 is essential for normal development and immune response. However, abnormal activation or mutations can contribute to diseases like certain cancers. Overall, STAT5 plays a key role in regulating how cells grow and respond to their environment.
