CATEGORY

SUBCELLULAR LOCALIZATION	extracellular
	intracellular
	intracellular,cytoplasm

basic FUNCTION	may be a stress protein involved in the control of bacterial proliferation
	inducing new pancreatic islets development
	stimulates beta-cell replication, by activating Akt kinase and increasing the levels of CCND1/CDK4
	secreted intestinal antimicrobial protein, can promote skin keratinocyte proliferation
	may potentially mediate the epidermal hyperproliferation observed in normal wound repair and in psoriasis
	downstream mediator of IL17A that enhances keratinocyte proliferation and downmodulates keratinocyte differentiation

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

INTERACTION

DNA

RNA

small molecule

protein	PDX-1 binds directly to the INGAP promoter (in a possible feedback loop to block unbridled pancreatic islet expansion)
	phosphorylated in response to extracellular stimuli by action of MAP3K1

cell & other

REGULATION

induced by

interleukin-17 (IL17) via activation of keratinocyte-encoded IL17 receptor A (IL-17RA)
