Research Backgrounds


Neuronal receptor tyrosine kinase that is essentially and transiently expressed in specific regions of the central and peripheral nervous systems and plays an important role in the genesis and differentiation of the nervous system. Transduces signals from ligands at the cell surface, through specific activation of the mitogen-activated protein kinase (MAPK) pathway. Phosphorylates almost exclusively at the first tyrosine of the Y-x-x-x-Y-Y motif. Following activation by ligand, ALK induces tyrosine phosphorylation of CBL, FRS2, IRS1 and SHC1, as well as of the MAP kinases MAPK1/ERK2 and MAPK3/ERK1. Acts as a receptor for ligands pleiotrophin (PTN), a secreted growth factor, and midkine (MDK), a PTN-related factor, thus participating in PTN and MDK signal transduction. PTN-binding induces MAPK pathway activation, which is important for the anti-apoptotic signaling of PTN and regulation of cell proliferation. MDK-binding induces phosphorylation of the ALK target insulin receptor substrate (IRS1), activates mitogen-activated protein kinases (MAPKs) and PI3-kinase, resulting also in cell proliferation induction. Drives NF-kappa-B activation, probably through IRS1 and the activation of the AKT serine/threonine kinase. Recruitment of IRS1 to activated ALK and the activation of NF-kappa-B are essential for the autocrine growth and survival signaling of MDK.


Phosphorylated at tyrosine residues by autocatalysis, which activates kinase activity. In cells not stimulated by a ligand, receptor protein tyrosine phosphatase beta and zeta complex (PTPRB/PTPRZ1) dephosphorylates ALK at the sites in ALK that are undergoing autophosphorylation through autoactivation. Phosphorylation at Tyr-1507 is critical for SHC1 association.

Application: WB    Species: Mouse    Sample:

Fig. 3. Phosphorylated-ALK is involved in the S. pneumoniae infection-induced NLRP3 inflammasome activation. A-B: PECs were infected with S. pneumoniae at an MOI of 5 for 0, 5, 15, 30 or 60 min. A: The cell lysates were collected, and total and phosphorylation levels of ALK were detected by western blot. B: P-ALK/t-ALK was analyzed by relative densitometric quantification. C-J: PECs were pretreated with or without ALK inhibitor (Bri, 20nmol/L) for 2 h and then infected with S. pneumoniae (MOI of 5) for 6 h. C-F: The protein expression levels of pro-caspase-1, p20, pro-IL-1β and p17 in supernatants or cell lysates were detected by western blot and analyzed by relative densitometric quantification. G: The mRNA expression levels of Caspase-1 and Il-1β were quantified by RT-PCR. H: The protein expression level of NLRP3 were detected by western blot and analyzed by relative densitometric quantification. I: The mRNA expression level of Nlrp3 was detected by RT-PCR.

K: PECs were pretreated with or without Bri for 2 h and then infected with S. pneumoniae (MOI of 1) for 24 h.The supernatants were collected and the level of IL-1β in supernatants were detected by ELISA. L-N: PECs were pretreated with or without Bri for 2 h and then infected with S. pneumoniae (MOI of 5) for 6 h. L: The protein expression level of NEK7 were detected by western blot and analyzed by relative densitometric quantification. M: The mRNA expression level of Nek7 was detected by RT-PCR. N: The NEK7-NLRP3 complex formation were detected by Co-IP. Similar results were obtained in three independent experiments in data. Data shown are means ± SEMs; *P
