Beta-thymosins constitute a group of small actin-sequestering peptides. These highly conserved peptides are involved in cytoskeleton dynamics and can influence different cell properties such as motility, substrate adhesion, shape and chemotaxis. As a marker for tumour metastasis, the mammalian thymosin beta15 is believed to have an important diagnostic relevance in cancer prognosis, although little is known about its physiological function. In order to study the role ofthymosin beta15avianin embryogenesis, we cloned the chicken and quail orthologues ofthymosin beta15and used the chicken as a model for vertebrate development. Avianthymosin beta15, the first known non-mammalianthymosin beta15-like gene, encodes a peptide that possesses a cysteine at position one after the methionine which is a significant difference compared to its mammalian counterparts.Thymosin beta15avianexpression starts at an early stage of development. The expression pattern changes rapidly with development and differs from that of the relatedthymosin beta4gene. The most prominent expression domain is seen in developing muscles of limbs and trunk. Gain-of-function experiments revealed that thymosin beta15avianhas a function in normal myotome development. Ectopic over-expression ofthymosin beta15avianleads to premature elongation of myotome cells trespassing segment borders. We conclude thatthymosin beta15avianhas a still undescribed function in promoting myocyte elongation.
