Chondrolectin is a protein that in humans is encoded by the CHODL gene.[1][2] Mouse chondrolectin is encoded by Chodl.[3]
Structure
Chondrolectin is a type I membrane protein with a carbohydrate recognition domain characteristic of C-type lectins in its extracellular portion.[1][3] In other proteins, this domain is involved in endocytosis of glycoproteins and exogenous sugar-bearing pathogens.[4] This protein has been shown to localise to the perinucleus.[1][5][6]
Function
The exact function of chondrolectin is unknown but it has been show to be a marker of fast motor neurons in mice,[6] and is involved in motor neuron development and growth in zebrafish (danio rerio).[7] Furthermore, human chondrolectin has been shown to localise to motor neurons within the spinal cord.[8]
Clinical significance
Chondrolectin is alternatively spliced in the spinal cord of mouse models[9] of the neuromuscular disease, spinal muscular atrophy (SMA), which predominantly affects lower motor neurons.[8] Increased levels of chondrolectin in a zebrafish model of SMA results in significant improvements in disease-related motor neuron defects.[10]
