Signal Transduction between human cells can be achieved through direct contact between adjacent cells. Specific primary antibodies can be found and selected to target proteins involved in key cell signal transduction pathways: extracellular growth factor, membrane receptor, GTPase, protein kinase, response element, binding protein and transcription factor. Popular signal transduction pathways and related proteins include MAPK / ERK pathway, Akt pathway, Wnt pathway, phosphorylated proteins (serine or tyrosine phosphorylated proteins) and transcription factors.
