SnRK
Sucrose non-fermenting-1 (SNF1)-related protein kinase
SnRKs are a highly conserved family of serine/threonine protein kinases, homologous to yeast SNF1 and animal AMPK, and can be divided into three subtypes: SnRK1, SnRK2, and SnRK3. SnRK1 is regulated upstream by sugar/energy signals and SnAK/GRIK kinases, and downstream by nitrate reductase, sucrose phosphate synthase, and bZIP transcription factor. SnRK2 is regulated core-by-core by the ABA-PYR/PYL-PP2C module and targets AREB/ABF transcription factor and the SLAC1 channel. SnRK3 interacts with the CBL calcium receptor and targets ion transporters such as SOS1 and AKT1. This kinase family is primarily responsible for plant energy balance, abscisic acid signal transduction, and responses to abiotic stresses (drought, high salinity, low temperature, flooding, and nutrient deficiency). Functions such as response, maintenance of ion homeostasis and regulation of growth and development are the core molecular targets for crop stress resistance, disease resistance and yield improvement. Related research is mainly applied to the fields of plant stress biology and crop genetic improvement, such as agricultural crop stress resistance breeding, food security and climate adaptability improvement[1][2].

AMARA peptide TFA
0 ImagesCat. No.: HY-P1576APurity: 98.53%AMARA peptide TFA is a synthetic peptide substrate of sucrose non-fermenting-1-related protein kinase 1 (SnRK1). AMARA peptide TFA contains residues required for SnRK1 phosphorylation, retains the minimal motif recognized by SnRK1, and when this substrate is recognized by cauliflower SnRK1 HRK-A, the hydrophobic residues at the relative positions P-5 and P+4 of the phosphorylated serine require a critical spacing. AMARA peptide TFA can serve as a control substrate in peptide phosphorylation assays for the detection of SnRK1 activity in Arabidopsis thaliana, potato tuber tissues, and during SnRK1 purification.

RSS0680
0 ImagesRSS0680 is a small noncoding RNA (sRNA) targeting the mRNA ribosome binding site (RBS) and a PROTAC. RSS0680 competitively binds to RBS through the conserved CCUCCUCCC anti-Shine-Dalgarno (aSD) sequence and inhibits the translation initiation of target genes. RSS0680 can interact with the DUF1127 protein CcaF1, regulate its own stability and participate in bacterial oxidative stress defense, enhancing the host's resistance to heat shock and oxidative damage by affecting pathways such as C1 metabolism and pyruvate dehydrogenase complex. RSS0680 degrades AAK1, CDK1, CDK16, CDK2, CDK4, CDK6, EIF2AK4, GAK, LATSl, LIMK2, MAPK6, MAPKAPK5, MARK2, MARK4, MKNK2, NEK9, RPS6KB1, SIK2, SNRK, STK17A, STK17B, STK35, and WEEl. RSS0680 can be used to study diseases or disorders mediated by aberrant kinase activity and regulatory mechanisms of noncoding RNAs in α-proteobacteria[1][2].
