( acid phosphatase 1, soluble; activating transcription factor 2; casein kinase 2, 1 polypeptide; casein kinase 2, prime polypeptide; actinin, 2; and Homo sapiens growth factor receptor-bound protein2) within the growth factor signaling pathways are also affected. Tuning of the expressionln of genes of these pathways balances the differentiation and proliferation of epithelial and mesenchymal teat tissue and finally affects the shape and structyre of the teats.
