SUBCELLULAR LOCALIZATION

extracellular

basic FUNCTION	key factor enabling all these early T cell responses, including the occurrence of calcium transients
	promotes Ag-independent responses and increases the probability of cognate MHC-peptide encounter
	macrophages participate in lymphangiogenesis in idiopathic diffuse alveolar damage through CCL19-CCR7 signal
	CCL19/21 induced PI3K-dependent phosphorylation of Akt/protein kinase B, activation of the Rho/Rho-associated coiled-coil forming protein kinases/myosin light chain pathway and MAPKs phosphorylation
	CCL21 together with another CCR7 ligand, CCL19, direct the navigation and compartmentation of T cells within secondary lymphoid tissues
	controls signaling events in T cells

CELLULAR PROCESS

cell migration & motility

PHYSIOLOGICAL PROCESS

immunity/defense

text	immune response

PATHWAY

metabolism

signaling

signal transduction

a component

part of CCL19, CCL21/CCR7 chemokine system expressed in inflamed muscles of polymyositis and may be involved in the pathomechanism of polymyositis

INTERACTION

DNA

RNA

small molecule

protein	ligand for the orphan receptor EBI1 (CMKBR7)
	ligand of CCR7
	specific ligand for CCRL2 (CCL19 is known to be critically involved in lymphocyte and dendritic cell trafficking, and CCL19-binding competition by CCRL2 might be involved in modulating these processes)
	FHL2 is a novel regulator of CCL19-induced dendritic cell (DC) migration
	CCL19 stimulation of na
	ve T cells regulates expression of MAPK7, KLF2, and S1PR1
	CCL19 controls T cell regulation of S1PR1 expression
	after binding to CCL19, CCR7 signaling leads to increased expression and phosphorylation of MAPK7 and up-regulation of KLF2, which results in S1PR1 expression and a migration of T lymphocytes
