Rabbit Anti-APG4B/FITC Conjugated antibody
background:
Autophagy is the process by which endogenous proteins and damaged organelles are destroyed intracellularly. Autophagy is postulated to be essential for cell homeostasis and cell remodeling during differentiation, metamorphosis, non-apoptotic cell death, and aging. Reduced levels of autophagy have been described in some malignant tumors, and a role for autophagy in controlling the unregulated cell growth linked to cancer has been proposed. This gene encodes a member of the autophagin protein family. The encoded protein is also designated as a member of the SLC54 family of cysteine proteases. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]
Function:
Cysteine protease required for autophagy, which cleaves the SLCterminal part of either MAP1LC3, GABARAPL2 or GABARAP, allowing the liberation of form I. A subpopulation of form I is subsequently converted to a smaller form (form II). Form II, with a revealed SLCterminal glycine, is considered to be the phosphatidylethanolamine (PE)-conjugated form, and has the capacity for the binding to autophagosomes.
Subcellular Location:
Cytoplasm (Probable).
Tissue Specificity:
Mainly expressed in the skeletal muscle, followed by brain, heart, liver and pancreas.
Similarity:
Belongs to the peptidase C54 family.

细胞自噬（Autophagy）是一种非凋亡性的程序性细胞死亡即自噬性程序性细胞死亡，进化过程中高度保守，清除降解细胞内受损伤的细胞结构、衰老的细胞器、以及不再需要的生物大分子等，在细胞的生长、发育和疾病发生中起着重要的作用。细胞自噬是一个高效调控过程，特异性激酶和鸟嘌呤核苷酸磷酸酶（GTPases）在调节自噬通道活性中起着关键作用.
