摘要：

A 886 bp cDNA encoding the murine rac1 protein has been isolated. The abundance of rac1 mRNA was determined in fourteen tissues from both mouse and pig. The mRNA 5' non-coding sequence is very rich in G + C, and has the potential to form several stable secondary structures. In addition, this region contains a putative open reading frame of 57 amino acids. Disruption of the actin microfilament network by cytochalasin B in LLC-PK1 cells results in down regulation of rac1 mRNA. In agreement with the proposed role of rac1 in exocytosis, these results could explain the inhibitory effect of cytochalasin B on secretory processes.
