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]
