Western blotting is a method for detecting a certain protein in a complex sample based on the specific binding of antigen and antibody. Different proteins can be divided into bands based on different mobility rates. The mobility is affected by many factors, which may cause the observed band size to be inconsistent with the expected size. The common factors include: 1. Post-translational modifications: For example, modifications such as glycosylation, phosphorylation, methylation, and acetylation will increase the molecular weight of the protein. 2. Splicing variants: Different expression patterns of various mRNA splicing bodies may produce proteins of different sizes. 3. Post-translational cleavage: Many proteins are first synthesized into precursor proteins and then cleaved to form active forms, such as COL1A1. 4. Relative charge: the composition of amino acids (the proportion of charged amino acids and uncharged amino acids). 5. Formation of multimers: For example, in protein dimer, strong interactions between proteins can cause the bands to be larger. However, the use of reducing conditions can usually avoid the formation of multimers. If a protein in a sample has different modified forms at the same time, multiple bands may be detected on the membrane. |

| background | The protein encoded by this gene is a member of the MAP kinase family. MAP kinases,also known as extracellular signal-regulated kinases (ERKs),act in a signaling cascade that regulates various cellular processes such as proliferation,differentiation,and cell cycle progression in response to a variety of extracellular signals. This kinase is activated by upstream kinases,resulting in its translocation to the nucleus where it phosphorylates nuclear targets. Alternatively spliced transcript variants encoding different protein isoforms have been described,This gene encodes a member of the MAP kinase family. MAP kinases,also known as extracellular signal-regulated kinases (ERKs),act as an integration point for multiple biochemical signals,and are involved in a wide variety of cellular processes such as proliferation,differentiation,transcription regulation and development. The activation of this kinase requires its phosphorylation by upstream kinases. Upon activation,this kinase translocates to the nucleus of the stimulated cells,where it phosphorylates nuclear targets. One study also suggests that this protein acts as a transcriptional repressor independent of its kinase activity. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions. Two alternatively spliced transcript variants encoding the same protein,but differing in the UTRs,have been reported for this gene. |
