Western blot analysis of extracts from MCF-7 (lane 2(20μg), MCF-7 (lane 3(40μg), using ULK1 Antibody. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody and Loading control antibody (Beta Actin, HY-P80438, 1/3000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (HY-P8004/HY-P8001, 1/10,000) was used for 1 hour at room temperature. -
Immunohistochemical analysis of paraffin-embedded Mouse brain tissue using ULK1 Antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 8.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HY-P80366, 1/200) in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX. -

Background

Function
ULK1 is a serine/threonine kinase and a key initiator of mammalian autophagy, functioning near the apex of a nutrient-sensitive regulatory pathway[1]. Mechanistically, AMPK binds ULK1 and supports ULK1-mediated autophagy, while mTORC1 negatively regulates the ULK1 autophagic complex through phosphorylation-dependent control[2][3]. During starvation, ULK1 links cellular energy sensing to downstream autophagy machinery, including ATG13, FIP200/RB1CC1, ATG101, ATG14L, VPS34, and phagophore formation[3][4]. In disease models, altered ULK1 signaling has been connected with prostate cancer progression, prion infection, clear cell renal cell carcinoma, cardiomyocyte oxidative injury, and pathogen-related autophagy[5][6][7][8][9]. Compared with ULK2, ULK1 shows strong functional overlap in nutrient-starvation autophagy, because combined ULK1/ULK2 loss disrupts autophagy activation more clearly than single loss[10]. Compared with ULK3, ULK1 remains part of the canonical mTOR-AMPK autophagy axis, whereas ULK3 can support mTOR-insensitive autophagic flux in BIN1-deficient hippocampal neurons[11]. For experimental applications, ULK1 pathway modulation can be studied with AMPK activators, mTOR inhibitors, deubiquitinase inhibitor WP1130, and pathway inhibitors targeting CAMKK2-AMPK-ULK1 signaling[2][5][12].

Subunit
Interacts with GABARAP and GABARAPL2 (PubMed:11146101). Interacts (via C-terminus) with ATG13 (PubMed:18936157). Part of a complex consisting of ATG13, ATG101, ULK1 and RB1CC1 (PubMed:19287211). Associates with the mammalian target of rapamycin complex 1 (mTORC1) through an interaction with RPTOR; the association depends on nutrient conditions and is reduced during starvation (PubMed:19211835, PubMed:21795849). Interacts with FEZ1; SCOC interferes with FEZ1-binding (PubMed:22354037). Interacts with TBC1D14 (PubMed:22613832). Interacts (phosphorylated form) with TRIM5 (PubMed:25127057). When phosphorylated at Ser-317, interacts with MEFV and BECN1 simultaneously (PubMed:26347139). Interacts with TRIM21 and IRF3, in the presence of TRIM21 (PubMed:26347139). Interacts with SESN2 (PubMed:25040165). Interacts with SQSTM1 (PubMed:25040165). Interacts with C9orf72 (PubMed:27334615). Interacts with WDR45 (PubMed:28561066). Interacts with ATG13; this interaction is increased in the absence of TMEM39A (PubMed:31806350). Interacts with WIPI2 (PubMed:28890335). Interacts with ATP2A2 (PubMed:28890335). Interacts with AMBRA1 (PubMed:25438055, PubMed:31123703). Interacts with IRGM; promoting the coassembly of ULK1 and BECN1 (PubMed:25891078)
