Chondrolectin is a protein that in humans is encoded by the CHODL gene.^[4][5] Mouse chondrolectin is encoded by Chodl.^[6]

Structure

Chondrolectin is a type I membrane protein with a carbohydrate recognition domain characteristic of C-type lectins in its extracellular portion.^[4][6] In other proteins, this domain is involved in endocytosis of glycoproteins and exogenous sugar-bearing pathogens.^[7] This protein has been shown to localise to the perinucleus.^[4][8][9]

Function

The exact function of chondrolectin is unknown but it has been show to be a marker of fast motor neurons in mice,^[9] and is involved in motor neuron development and growth in zebrafish (danio rerio).^[10] Furthermore, human chondrolectin has been shown to localise to motor neurons within the spinal cord.^[11]

Clinical significance

Chondrolectin is alternatively spliced in the spinal cord of mouse models^[12] of the neuromuscular disease, spinal muscular atrophy (SMA), which predominantly affects lower motor neurons.^[11] Increased levels of chondrolectin in a zebrafish model of SMA results in significant improvements in disease-related motor neuron defects.^[13]
