ATXN2 and neoplasm: ATXN2 interacts with a wide range of proteins, but a comprehensive understanding of its interaction network and the role of these interactions in disease needs to be further investigated.ATXN2 was found to be immunologically relevant early on, but little research has been carried out in the area of immunity.ATXN2 is involved in tumour progression, but the specific mechanisms involved remain understudied in the field.ATXN2 has been found to be a major contributor to the development of tumours, but the specific mechanisms involved remain understudied.
