Chondrolectin is a protein that in humans is encoded by the CHODL gene. ^{[5] [6]} Mouse chondrolectin is encoded by Chodl. ^[7]

Structure

Chondrolectin is a type I membrane protein with a carbohydrate recognition domain characteristic of C-type lectins in its extracellular portion. ^{[5] [7]} In other proteins, this domain is involved in endocytosis of glycoproteins and exogenous sugar-bearing pathogens. ^[8] This protein has been shown to localise to the perinucleus. ^{[5] [9] [10]}

Function

The exact function of chondrolectin is unknown but it has been shown to be a marker of fast motor neurons in mice, ^[10] and is involved in motor neuron development and growth in zebrafish (Danio rerio). ^[11] Furthermore, human chondrolectin has been shown to localise to motor neurons within the spinal cord. ^[12]

Clinical significance

Chondrolectin is alternatively spliced in the spinal cord of mouse models ^[13] of the neuromuscular disease, spinal muscular atrophy (SMA), which predominantly affects lower motor neurons. ^[12] Increased levels of chondrolectin in a zebrafish model of SMA results in significant improvements in disease-related motor neuron defects. ^[14]
