CCL15
Function
Chemotactic factor that attracts T-cells and monocytes, but not neutrophils, eosinophils, or B-cells. Acts mainly via CC chemokine receptor CCR1. Also binds to CCR3. CCL15(22-92), CCL15(25-92) and CCL15(29-92) are more potent chemoattractants than the CCL15.
Post-translational modifications
The N-terminal is proteolytically cleaved by proteases associated with inflammatory responses. The processed forms CCL15(22-92), CCL15(25-92) and CCL15(29-92) exhibit increase in CCR1-mediated signaling and chemotaxis assays in vitro.
Sequence Similarities
Belongs to the intercrine beta (chemokine CC) family.
Tissue Specificity
Most abundant in heart, skeletal muscle and adrenal gland. Lower levels in placenta, liver, pancreas and bone marrow. CCL15(22-92), CCL15(25-92) and CCL15(29-92) are found in high levels in synovial fluids from rheumatoid patients.
