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 | Protein tyrosine kinase that is part of several cell surface receptor complexes, but that apparently needs a coreceptor for ligand binding. Essential component of a neuregulin-receptor complex, although neuregulins do not interact with it alone. GP30 is a potential ligand for this receptor. Regulates outgrowth and stabilization of peripheral microtubules (MTs). Upon ERBB2 activation, the MEMO1-RHOA-DIAPH1 signaling pathway elicits the phosphorylation and thus the inhibition of GSK3B at cell membrane. This prevents the phosphorylation of APC and CLASP2, allowing its association with the cell membrane. In turn, membrane-bound APC allows the localization of MACF1 to the cell membrane, which is required for microtubule capture and stabilization.In the nucleus is involved in transcriptional regulation. Associates with the 5'-TCAAATTC-3' sequence in the PTGS2/COX-2 promoter and activates its transcription. Implicated in transcriptional activation of CDKN1A; the function involves STAT3 and SRC. Involved in the transcription of rRNA genes by RNA Pol I and enhances protein synthesis and cell growth. |
