COL26A1 encodes a protein containing an emilin domain and two collagen stretches. This gene may be associated with aspirin-intolerant asthma. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. COL26A1 (Collagen Type XXVI Alpha 1 Chain) is a Protein Coding gene. Among its related pathways are Degradation of the extracellular matrix and Collagen chain trimerization. An important paralog of this gene is EMID1.
