Figure S1. Introducing shorter NCAM sequences into the CEA sequence of 1C. (A) Representation of the amino acids in 1C that were replaced with the corresponding amino acids from NCAM, with the FACS means in LR cells indicated. (B) All chimeric constructs were GPI anchored, as shown by Triton X-100 insolubility (top) and PIPLC sensitivity (bottom). (C) All proteins retained the ability to mediate intercellular adhesion, which is similar to the 1C construct. (D) Effect of these chimeras on LR Fn binding. Values represent the relative mean ± SEM (error bars) for six independent experiments (*, P
