Oligomerization in Fluorescent Proteins (FP) hinders the usage as a marker for protein tagging. The problems include but not limited to abnormal localization, interfering with signaling cascades and disturing the normal function of tagged proteins. Predicting the oligomeric States of Fourescent protein may help live biomedical imaginngs and fasten the efforts in creating monomeric FP. Thus, the webserver is dedicated to predict the oligomeric states of FP using only sequence informations to determine whether uploaded sequences are Oligomeric or Monomeric FP.
