HY-W794670

H-Ala-Pro-Ala-OH	Aminopeptidase	Others
H-Ala-Pro-Ala-OH, tripeptide, is a substrate for Escherichia coli PepP (Xaa-Pro *aminopeptidase). H-Ala-Pro-Ala-OH acts as a nitrogen source for wild-type Escherichia coli* .

HY-183739

CQ31	Pyroptosis Caspase	Cancer
CQ31 is a PEPD and XPNPEP1 inhibitor, with an IC₅₀ of 0.67 μM against PEPD and an IC₅₀ of 122 μM against XPNPEP1. CQ31 inhibits the M24B aminopeptidase activity of PEPD and XPNPEP1. CQ31 induces the accumulation of Xaa-Pro-containing peptides, mildly inhibits DPP8/9, and triggers CASP1-dependent pyroptosis via activation of the CARD8 inflammasome and caspase-1. CQ31 can be used in research related to cancers such as acute myeloid leukemia .

HY-P71435

	XPNPEP3 Protein, Human (His) Probable Xaa-Pro aminopeptidase 3; X-Pro aminopeptidase 3; aminopeptidase P3; APP3; XPNPEP3	Human	E. coli
	The XPNPEP3 protein catalyzes the removal of prolyl residues from N-terminal peptides (such as Leu-Pro-Ala) and has low activity towards Ala or Ser at the P1 site. XPNPEP3 Protein, Human (His) is the recombinant human-derived XPNPEP3 protein, expressed by E. coli , with N-6His, C-6His labeled tag.

	Aminopeptidase P2 Protein, Rat (HEK293, His) is the recombinant rat-derived Aminopeptidase P2 protein, expressed by HEK293, with C-His tag.

HY-P703772

	Aminopeptidase P2 Protein, Mouse (HEK293, His) Xaa-Pro aminopeptidase 2; Membrane-bound aminopeptidase P; Membrane-bound APP; mAPP; X-Prolyl aminopeptidase 2; Xpnpep2;	Mouse	HEK293
	Aminopeptidase P2 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Aminopeptidase P2 protein, expressed by HEK293, with C-His tag.

HY-P700260

	Aminopeptidase P1 Protein, Human (His-SUMO) AminoacylProline aminopeptidase; aminopeptidase P, cytosolic; APP1; Cytosolic aminopeptidase P; RP11 451M19.1; sAmp; Soluble aminopeptidase P; soluble; X Pro aminopeptidase 1; X Prolyl aminopeptidase (aminopeptidase P) 1; X Prolyl aminopeptidase (aminopeptidase P) 1 soluble; X Prolyl aminopeptidase 1; X Prolyl aminopeptidase 1 soluble; X-Pro aminopeptidase 1; X-Prolyl aminopeptidase 1; Xaa Pro aminopeptidase 1; Xaa-Pro aminopeptidase 1; XPNPEP 1; XPNPEP; xpnpep1; XPNPEPL; XPNPEPL1; XPP1_HUMAN	Human	E. coli
	Aminopeptidase P1 Protein, a metalloaminopeptidase, crucially catalyzes the removal of penultimate prolyl residues from peptide N-termini, including substrates like Arg-Pro-Pro. This activity significantly contributes to specific peptide degradation, exemplified in bradykinin processing. Aminopeptidase P1's selective prolyl cleavage underscores its importance in modulating peptide structures and functions within biological systems. Aminopeptidase P1 Protein, Human (His-SUMO) is the recombinant human-derived Aminopeptidase P1 protein, expressed by E. coli , with N-6*His, N-SUMO labeled tag.

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
