IB1 is a mammalian scaffold protein that interacts with components of the c-Jun N-terminal kinase (JNK) signal-transduction pathway mainly via its protein-protein interaction domains. Crystallization of the key Src homology 3 (SH3) domain of IB1 has been achieved. Crystallization experiments with unmodified protein and deliberately oxidized protein have led to different crystal forms. X-ray data have been collected to 3.0 A resolution from a crystal form with rectangular prism morphology. These crystals are orthorhombic (P2(1)2(1)2(1)), with unit-cell parameters a = 45.9, b = 57.0, c = 145.5 A. These are the first crystallographic data on a scaffold molecule such as IB1 to be reported.

Chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia patients largely benefit from an expanding tyrosine kinase inhibitors (TKIs) toolbox that has improved the outcome of both diseases. However, TKI success is continuously challenged by mutation-driven acquired resistance and therefore, close monitoring of clonal genetic diversity is necessary to ensure proper clinical management and adequate response to treatment. Here, we report the case of a ponatinib-resistant Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph + ALL) patient harboring a BCR::ABL1 p.

Background: Among numerous genes that have been a focus of equine genetic research, the (Klotho) and (Alpha-actinin-3) genes stand out due to their significant roles in muscle function and overall health, as well as performance ability. Previous studies on Arabian horses and other mammalians have shown that both and occur in different isoforms that seem to have different roles in metabolism. The main purpose of this present study was to describe different isoforms (, , , , , ) expression levels affected by the endurance effort in Arabian horses.

The transcription factor p63 is expressed in many different isoforms as a result of differential promoter use and splicing. Some of these isoforms have very specific physiological functions in the development and maintenance of epithelial tissues and surveillance of genetic integrity in oocytes. The ASPP family of proteins is involved in modulating the transcriptional activity of the p53 protein family members, including p63.

Virus-host protein interaction is critical for successful completion of viral replication cycles. As the largest nonstructural protein (NSP) of porcine reproductive and respiratory syndrome virus (PRRSV), NSP2 plays multiple and critical roles in viral replication, antiviral immunity, cellular tropism and virulence. An interactome of this protein with host proteins would be instrumental in full understanding of these multifunctional roles.
