Biochem/physiol Actions

BS-I has a major affinity for terminal α-D-galactosyl residues with a secondary affinity for terminal N-acetyl-α-D-galactosaminyl residues.

Preparation Note

Purified by affinity chromatography using the method of Hayes, C. E., and Goldstein, I. J., J. Biol. Chem., 249, 1904 (1974).

Analysis Note

Agglutination activity is expressed in μg/mL and is determined from serial dilutions of a 1 mg/mL solution using phosphate buffered saline, pH 6.8, containing, for each lectin, calcium, magnesium, and manganese at different concentrations. This activity is the lowest concentration to agglutinate a 2% suspension of appropriate erythrocytes after 1 hr incubation at 25 °C.

Other Notes

BS-I is a tetrameric lectin consisting of two types of subunits designated A and B. There are five BS-I isolectins with different subunit composition: BSI-B₄, BSI-AB₃, BSI-A₂B₂, BSI-A₃B and BSI-A₄. BSI-B₄ is blood group B specific and has an exclusive affinity for terminal α-D-galactosyl residues, whereas BSI-A₄ has blood group A specificity and has a major affinity for terminal N-acetyl-α-D-galactosaminyl residues.

Acetylation stabilises calmodulin-regulated calcium signalling.

Karen Baker et al.

FEBS letters, 596(6), 762-771 (2022-02-01)

Calmodulin is a conserved calcium signalling protein that regulates a wide range of cellular functions. Amino-terminal acetylation is a ubiquitous post-translational modification that affects the majority of human proteins, to stabilise structure, as well as regulate function and proteolytic degradation.

Paired arrangement of kinetochores together with microtubule pivoting and dynamics drive kinetochore capture in meiosis I.

Gheorghe Cojoc et al.

Scientific reports, 6, 25736-25736 (2016-05-12)

Kinetochores are protein complexes on the chromosomes, whose function as linkers between spindle microtubules and chromosomes is crucial for proper cell division. The mechanisms that facilitate kinetochore capture by microtubules are still unclear. In the present study, we combine experiments

Matricellular Protein SPARCL1 Regulates Blood Vessel Integrity and Antagonizes Inflammatory Bowel Disease.

Daniela Regensburger et al.

Inflammatory bowel diseases, 27(9), 1491-1502 (2021-01-05)

The understanding of vascular plasticity is key to defining the role of blood vessels in physiologic and pathogenic processes. In the present study, the impact of the vascular quiescence marker SPARCL1 on angiogenesis, capillary morphogenesis, and vessel integrity was evaluated.

Exomer Is Part of a Hub Where Polarized Secretion and Ionic Stress Connect.

Sandra Moro et al.

Frontiers in microbiology, 12, 708354-708354 (2021-08-06)

Plasma membrane and membranous organelles contribute to the physiology of the Eukaryotic cell by participating in vesicle trafficking and the maintenance of ion homeostasis. Exomer is a protein complex that facilitates vesicle transport from the trans-Golgi network to the plasma

A novel live-cell imaging system reveals a reversible hydrostatic pressure impact on cell-cycle progression.

Holly R Brooker et al.

Journal of cell science, 131(15) (2018-06-23)

Life is dependent upon the ability of a cell to rapidly respond to changes in the environment. Small perturbations in local environments change the ability of molecules to interact and, hence, communicate. Hydrostatic pressure provides a rapid non-invasive, fully reversible
