Figure 7. ZFYVE27 is a peripheral membrane protein.

Figure 7

Sub-cellular fractionation was performed with NSC34 cell extract. The cytosolic fraction (S-100) and the membrane fraction (P-100) were analyzed by immunoblot with ZFYVE27 antibody. Asterisks denote the non-specific band. The monomeric ZFYVE27 (mo-ZFYVE27) and SDS-resistant dimeric ZFYVE27 (di-ZFYVE27) are indicated. The membrane fraction (P-100) was subjected to Triton X-114 phase separation and equal volumes of aqueous phase (peripheral) and detergent phase (integral) fractions were analyzed by immunoblotting. The blot was stripped and re-probed with COX4 antibody, a marker for the integral membrane protein.
