Galectin 1 - A galectin found abundantly in smooth muscle (MUSCLE, SMOOTH) and SKELETAL MUSCLE and many other tissues. It occurs as a homodimer with two 14 kD subunits. |
 |
Galectin 2 - A galectin found preferentially expressed in the gastrointestinal tract. The protein occurs as a homodimer with two 14 kD subunits. |
 |
Galectin 3 - A multifunctional galactin initially discovered as a macrophage antigen that binds to IMMUNOGLOBULIN E, and as 29-35 kD lectin that binds LAMININ. It is involved in a variety of biological events including interactions with galactose-containing glycoconjugates, cell proliferation, CELL DIFFERENTIATION, and APOPTOSIS. |
 |
Galectin 4 - A galectin found in the small and large intestine and the stomach. It occurs as a homodimer with two 36 kD subunits and is localized to sites of cell adhesion where it may play role in assembly of ADHERENS JUNCTIONS. |
