Gene naming is very important in proteomics and bioinformatics because it gives a definite identification to all discovered genes. I have seen where you are coming from that question but apparently, there are no differences between matK and MATK gene. When you are running database for example entrez gene, it would be like you are looking a query; meaning it is not case sensitive.
In related literature it is written as matK but in gene data bank it is written as MATK. Both of them mean that they encode Megakaryocyte-associated tyrosine kinase.
In connection with the naming of genes, researchers around the world have to be very specific in naming the genes that they have discovered. Therefore there should only be one specific sequence per name. For example the gene expressed on human cells of the HER family have variations such as HER1, HER2, HER3 and HER4. Instead of naming the other HER’s with a different name, they just add numbers for specifications.
but at some databases I found matK's mat stands for maturase, which helps in self splicing, that is what confused me....
