19551523 Hirschfeld J, Maurer J, Jung D, Kwiecinski M, Khimji AK, Dienes HP, Fries JW, Odenthal M: Targeting myofibroblasts in model systems of fibrosis by an artificial alpha-smooth muscle-actin promoter hybrid. Mol Biotechnol. 2009 Oct;43(2):121-9. Epub 2009 Jun 24.

An artificial promoter containing the -702 bp regulatory sequence of the alpha-smooth muscle actin (SMA) gene linked to the first intron enhancer sequence of the beta-actin gene and the beta-globin intron-exon junction was constructed and tested for myofibroblast-dependent gene expression using the green fluorescent protein as a reporter.

KH-type splicing regulatory protein (KSRP) is closely related to chick zipcode-binding protein 2 and rat MARTA1, which are involved in neuronal transport and localization of beta-actin and microtubule-associated protein 2 mRNAs, respectively.

These defects correlate with reduced beta-actin messenger RNA and protein levels in distal axons.

In this review, new findings regarding the dual cellular role of the SMN protein (translocation of beta-actin to axonal growth cones and snRNP biogenesis/pre-mRNA splicing) were integrated with recent data obtained by detailed neuropathological examination of SMA and control subjects.
