Gene Information

human ... HSPA4L(22824)

General description

Heat shock 70kDa protein 4L is a protein encoded by the HSPA4L gene in humans. Heat shock proteins HSPA4L and HSPA4 are closely related members of the HSP110 family and act as cochaperones.

Immunogen

Synthetic peptide directed towards the C terminal region of human HSPA4L

Application

Anti-HSPA4L antibody produced in rabbit is suitable for western blotting at a concentration of 1 μg/mL.

Biochem/physiol Actions

Hspa4l is expressed ubiquitously and predominantly in the testis and is highly expressed in spermatogenic cells. It plays an important role in osmotolerance. HSPA4L and HSPA4 collaborate in embryonic lung maturation and helps in air breathing during child birth. Osp94 also acts as molecular chaperone and possesses cytoprotective role from excessive stimulation from heat, hyper-ionic and osmotic stress which cause marked perturbation of intracellular protein function including the suppression of protein synthesis.

Sequence

Synthetic peptide located within the following region: KDERYDHLDPTEMEKVEKCISDAMSWLNSKMNAQNKLSLTQDPVVKVSEI

Physical form

Purified antibody supplied in 1x PBS buffer with 0.09% (w/v) sodium azide and 2% sucrose.

Osmotic stress protein 94 (OSP94), a member of the heat shock protein 110/SSE subfamily, is expressed in certain organs such as the kidney, testis, and brain where it can act as a molecular chaperon. In general, its alteration in expression

Heat shock proteins HSPA4L and HSPA4 are closely related members of the HSP110 family and act as cochaperones. We generated Hspa4l(-/-)Hspa4(-/-) mice to investigate a functional complementarity between HSPA4L and HSPA4 during embryonic development. Hspa4l(-/-)Hspa4(-/-) embryos exhibited marked pulmonary hypoplasia

The Hspa4l gene, also known as Apg1 or Osp94, belongs to the HSP110 heat shock gene family, which includes three genes encoding highly conserved proteins. This study shows that Hspa4l is expressed ubiquitously and predominantly in the testis. The protein
