Interactions

S100A10 has been shown to interact with TRPV5, TRPV6, TASK-1, ASIC1a, CTSB, BAD, KCNK3, UBC and ANXA2.

There is a specificity in the interaction between p11 and 5-HT1B. In a two-hybrid screen using twenty six out of 29 double-positive prey clones containing the gene encoding p11. This study showed that p11 interacted with 5-HT1B receptors but not with 5-HT1A, 5-HT2A, 5-HT5A, 5-HT6, dopamine D1 or D2 receptors, two irrelevant baits (C{Delta}115 and pRP21), or the empty plasmid. The specific interaction has been verified in three other ways: In HeLa cells and brain tissue p11 was found to coimmunoprecipitate with 5-HT1B receptors; Immunofluorescence studies show colocalization between p11 and 5-HT1B receptors at the cell surface; and distribution of p11 mRNA in the brain resembles that of 5-HT1B receptor mRNA. The table below shows the proteins that interact with p11 and the functional role of p11 in these interactions

Famous quotes containing the word interactions:

    “Whereas children can learn from their interactions with their parents how to get along in one sort of social hierarchy—that of the family—it is from their interactions with peers that they can best learn how to survive among equals in a wide range of social situations.”
    —Zick Rubin (20th century)

    “In our interactions with people, a benevolent hypocrisy is frequently required—acting as though we do not see through the motives of their actions.”
    —Friedrich Nietzsche (1844–1900)

    “The exercise of power is determined by thousands of interactions between the world of the powerful and that of the powerless, all the more so because these worlds are never divided by a sharp line: everyone has a small part of himself in both.”
    —Václav Havel (b. 1936)
