Figure Lengend Snippet: Knockdown of C16orf87 causes minor changes in the host cell protein profile. ( A ) Alignment of human ( Homo sapiens , UniProtKB accession number Q6PH81 ), mouse ( Mus musculus , UniProtKB accession number Q9CR55 ), and zebrafish ( Danio rerio , UniProtKB accession number Q6DGQ4 ) C16orf87 amino acid sequences. Alignment mismatches are indicated in gray boxes. The underlined sequence represents a possible minimal Akt/PKB kinase consensus recognition motif. A Ser91(S91) phosphorylation site is marked with an asterisk. ( B ) Per-residue confidence (pLDDT) coloring of the top-ranked predicted model of C16orf87. In the inset, the predicted zinc-ribbon domain is shown with the zinc-interacting cysteines (Cys16, Cys19, Cys30, and Cys32) indicated around the zinc ion (Zn 2+ ). The position of the phosphorylated serine (Ser91), a putative alpha-helix between amino acid residues Ser-107 and Ala-126, and the confidently predicted C-terminal alpha-helix between amino acid residues Asp-130 and Ile-153 are also highlighted. The ipTM and pTM values are annotated. N, N-terminus; C, C-terminus. Figure was rendered using ChimeraX (version 1.8, https://www.rbvi.ucsf.edu/chimerax ) ( C ) Western blot (WB) analysis of C16orf87 siRNA (siC16) knockdown in Panc-01, MiaPaCa-2, and C2C12 cell lines. A non-specific, scrambled siRNA (siScr) was used as a control; the WB membrane was probed with the antibodies against C16orf87 and actin. MS-based proteomics analysis of siRNA-treated C2C12 ( D ), MiaPaCa-2 ( E ), and Panc-01 ( F ) cells. Data points corresponding to histones are colored in pink, and statistically significant ( P < 0.05, fold-change > 1) proteins are colored in yellow (mouse cell line C2C12) and green (human cell lines, Panc-01 and MiaPaCa-2).
