Detect the subcellular location of eukaryotic protein sequences based on the predicted presence of any of the N-terminal presequences chloroplast transit peptide (cTP), mitochondrial targeting peptide (mTP) or secretory pathway signal peptide (SP). They are synthesized in the nucleocytoplasm as preproteins with N-terminal extensions (transit peptides, targeting Adegbaju MS, Morenikeji OB, Borrego EJ, Hudson AO, Thomas BN. Once a preprotein reaches the stromal side of the chloroplast envelope and its transit peptide has been cleaved off by the stromal processing peptidase, in many cases, the protein is further targeted to its correct sub-compartment within the chloroplast (Schleiff and Becker, 2011. In contrast, proteins with a transit peptide are recognized by cytosolic factors such as Hsp70, Hsp90 and 14‐3‐3 after translation and then delivered to various types of import receptors localized to the chloroplast OEMs. The transit peptides of chloroplast preproteins are generally larger and more diverse than the targeting signals for other organellar proteins (Kim and Hwang, 2013), and transit peptides have evolved to mediate tissue-specific or age-dependent import of specific classes of preproteins (Teng et al., 2012; Li and Teng, 2013). Many of the chloroplast's protein complexes consist of subunits from both the chloroplast genome and the host's nuclear genome. In some embodiments, the disclosure concerns methods for producing a transgenic plant material (e.g., a transgenic plant) comprising a chloroplast transit peptide, as well as plant materials produced by such methods, and plant commodity products produced therefrom.

Overview. At a primary structural level, transit peptide sequences are highly divergent in length, composition and organization. At a primary structural level, transit peptide sequences are highly divergent in length, composition and organization. This is in contrast to our hypothesis and in silico prediction and shows that removing 12–15 N‐terminal amino acids from a chloroplast transit peptide, does not redirect the proteins from chloroplasts to mitochondria, but inhibits import into both organelles. You can also look at abbreviations and acronyms with word CTP in term. 2001 Dec 12;1541(1-2):2-21. doi: 10.1016/s0167-4889(01)00149-5. The cleavage of transit peptides during import is likely to be essential for chloroplast biogenesis and function. The transit peptide is required for their transport across the relevant membranes from their site of synthesis in the cytoplasm. Structure. At a primary structural level, transit peptide sequences are highly divergent in length, composition and organization. Stromal processing peptidase binds transit peptides and initiates their ATP-dependent turnover in chloroplasts. Methods and compositions are provided for targeting a polypeptide of interest to a chloroplast. These functions include direct interaction with envelope lipids, chloroplast receptors and the stromal processing peptidase. Most chloroplast proteins (cp proteins) are nucleus-encoded, synthesized on cytosolic ribosomes as precursor proteins containing a presequence (cTP), and post-translationally imported via the Tic/Toc complex into the organelle, where the cTP is removed. TargetP provides a potential cleavage site for sequences predicted to contain a cTP, mTP or SP. TargetP-2.0 server predicts the presence of N-terminal presequences: signal peptide (SP), mitochondrial transit peptide (mTP), chloroplast transit peptide (cTP) or thylakoid luminal transit peptide (luTP). 1986 Aug 1;46(3):365-75. doi: 10.1016/0092-8674(86)90657-4. eCollection 2020.

The genomic organization of transit peptides suggests that these domains might have originated from distinct exons, which were shuffled and streamlined throughout evolution to yield a modern, multifunctional transit peptide. At a primary structural level, transit peptide sequences are highly divergent in length, composition and organization. The plasticity of transit peptide design is consistent with the diverse biological functions of chloroplast proteins. Protein import into chloroplasts requires a transit peptide, which interacts with the chloroplast transport apparatus and leads to translocation of the protein across the chloroplast envelope. The transit peptide is required for their transport across the relevant membranes from their site of synthesis in the cytoplasm. Chloroplast function is dependent on the import of thousands of proteins from the cytosol across the two membranes of the chloroplast envelope via the TOC (translocon at the outer chloroplast envelope) and TIC. 2020 Sep 25;11:560701. doi: 10.3389/fpls.2020.560701.
