Figure 3.

Salient features of the ALN predicted amino acid sequence. (a) ALN sequence with predicted signal sequence (underlined), putative PEST motif (inverse), undecapeptide (bold), and cholesterol-interacting TL motif (double underlined). (b) Undecapeptide sequences of ALN, other CDC undecapeptides known to differ from consensus, and the consensus CDC undecapeptide. The cysteine conserved in thiol-activated CDCs (but absent from ALN) is underlined in the consensus sequence. Differences from consensus depicted as inverse letters. Abbreviations as in Figure 2.
