TLDR Crimped wool has proteins linked to crimp formation, while straight wool has proteins linked to fiber fineness, which can improve wool quality and value.

The study on Chinese Tan sheep wool identified 1,218 proteins, with 213 differentially expressed between crimped and straight wool. Crimped wool had higher levels of proteins like KAP24-1 and K84, while straight wool had more K6A and trichohyalin. These differences in protein expression influence wool morphology, offering insights into wool crimp formation and potential improvements in wool quality for the textile industry. The study involved four 35-day-old Tan sheep, enhancing the understanding of wool characteristics and their economic potential.
