Role of E3 Ligase UBR5 in Alternative Splicing during B Cell Development and Activation

ABSTRACT Proper B cell development is an essential part of innate and adaptive immunity. Coordination of a number of molecular mechanisms are required to facilitate B cell development, maturation, activation, and survival of B cells. Recently, the ubiquitin E3 ligase, UBR5 has been found mutated in a significant number of cases of patients with mantle cell lymphoma, implicating the E3 ligase in B cell development. UBR5 is a key regulator of DNA damage repair, transcription, translation, and our data suggests mRNA splicing via the spliceosome. UBR5 is a HECT domain ligase, which contains a cysteine residue that is responsible for ubiquitin transfer to its substrates. To elucidate the role of…
