Amino Acid Sequence

Trp-His-Trp-Leu-Gln-Leu

Application

Trp-His-Trp-Leu-Gln-Leu (WHWLQL) was used as an internal standard in multiplex serum protein assay for evaluating the individual′s probability of having colorectal cancer (CRC).

Biochem/physiol Actions

Trp-His-Trp-Leu-Gln-Leu (WHWLQL) is the peptide fragment of alpha1-mating factor secreted by yeast that facilitates in the regulation of mating. Alpha1-mating factor can arrest many yeast strains in the G1-phase of the cell cycle.

Synchronously dividing haploid yeast cells were UV-irradiated in various stages of the cell cycle after release from alpha-factor arrest. In confirmation of earlier results (Chanet et al., 1973), in wild-type strains G1/S phase cells were found to be the most
