reach
"Thus, cytokines other than IL-2, such as IL-15, which bind to IL-2Rbeta and gammac, are important for the development of NK, NK + alphabeta T and gammadelta T cells."

reach
"IL-2 and IL-15 each bind the gamma (c) receptor (CD132), which signals through JAK1."

reach
"IL-15 shares many similarities to IL-2 as it also binds to CD122 and gammac."

reach
"In the absence of IL-15Ralpha, the beta and gammaC complex binds IL-15 with an intermediate affinity and is capable of mediating responses [XREF_BIBR]."

reach
"IL-15Rbeta (also known as IL-2Rbeta or CD122) and IL-15Rgamma c (also known as CD132) can bind to both IL-15 and IL-2 with intermediate affinity."

reach
"In EAE, the upregulation of IL2RG and other IL15 binding receptors is widespread."

reach
"Furthermore, IL-15 binds to gamma c with considerably lower shape complementarity than IL-2 or IL-4 (sc = 0.59 for IL-15 versus 0.84 for IL-2 and 0.82 for IL-4)."

"The common gamma-chain (gamma(c)) is an indispensable subunit of the functional receptor complexes for il-4, il-7, il-9, and il-15 as well as il-2. Here we show that the gamma(c) is also shared with the il-21r complex."

reach
"IL2, IL4, IL7, IL9, IL15, and IL21, all interact with the common gammac (IL2Rgamma) via the gammac box present in their D-helices 17."

reach
"At its site II interface, IL-15 binds to gamma c through a rather chemically ' featureless ' interface that stands in stark contrast to the highly polar and specific side chains contacts seen in the site I interface."

sparser
"These results strongly suggest that the gamma c chain transduces major signal(s) involved in NK cell differentiation from hematopoietic progenitor cells and that IL-15 interaction with gamma c is involved in this process at an earlier step than IL-2/IL-7 interactions of gamma c are."

reach
"Recently two modifications of IL-2 have been generated that block binding of normal IL-2 and IL-15 to IL-2 and IL-15Rbeta and gammac receptors, thereby simultaneously inhibiting the actions of both IL-2 and IL-15."

reach
"The binding of IL2 or IL15 to the IL2 and IL15Rbeta and gammac heterodimer induces JAK1 activation via the beta chain and JAK3 via the gamma chain that together phosphorylate tyrosine on the cytokine receptors and induce the tyrosine phosphorylation of STAT3, STAT5A and STAT5B that via SH2 domain interactions homodimerize, translocate to the nucleus and bind to regulatory regions of target genes."

sparser
"In contrast, IL-15 signaling is initiated by binding of IL-15 to the IL-15Rβ and γC molecules on the cell surface, which activates JAK1 and 3, followed by activation of STAT5 ( xref )."
