Figure 2. Identification, annotation and classification of proteins in the silk gland lumen.

Figure 2

(A) LC-MS/MS identified 1271 proteins in the silk gland lumen, 295 proteins of them was identified as silk proteins (Dong et al. 2013; Zhang et al. 2015), and 262 proteins were predicted as secretory proteins by Phobius website (Supplementary Dataset 2). The secretory proteins contain signal peptides but no transmembrane regions. (B) The relative abundances of silk proteins and predicted secretory proteins in the lumen of silk gland. (C) The relative abundances of the proteins in the silk gland lumen according to their functional categories. The protein abundances were calculated with intensity-based absolute quantification (iBAQ).
