    • Target

    • Function

      Binds to the patched (PTC) receptor, which functions in association with smoothened (SMO), to activate the transcription of target genes. In the absence of SHH, PTC represses the constitutive signaling activity of SMO. Also regulates another target, the gli oncogene. Intercellular signal essential for a variety of patterning events during development: signal produced by the notochord that induces ventral cell fate in the neural tube and somites, and the polarizing signal for patterning of the anterior-posterior axis of the developing limb bud. Displays both floor plate- and motor neuron-inducing activity. The threshold concentration of N-product required for motor neuron induction is 5-fold lower than that required for floor plate induction.

    • Tissue specificity

      Expressed in fetal intestine, liver, lung, and kidney. Not expressed in adult tissues.

    • Involvement in disease

      Defects in SHH are the cause of microphthalmia isolated with coloboma type 5 (MCOPCB5) [MIM:611638]. Microphthalmia is a clinically heterogeneous disorder of eye formation, ranging from small size of a single eye to complete bilateral absence of ocular tissues. Ocular abnormalities like opacities of the cornea and lens, scaring of the retina and choroid, cataract and other abnormalities like cataract may also be present. Ocular colobomas are a set of malformations resulting from abnormal morphogenesis of the optic cup and stalk, and the fusion of the fetal fissure (optic fissure).
      Defects in SHH are the cause of holoprosencephaly type 3 (HPE3) [MIM:142945]. Holoprosencephaly (HPE) [MIM:236100] is the most common structural anomaly of the brain, in which the developing forebrain fails to correctly separate into right and left hemispheres. Holoprosencephaly is genetically heterogeneous and associated with several distinct facies and phenotypic variability. The majority of HPE3 cases are apparently sporadic, although clear examples of autosomal dominant inheritance have been described. Interestingly, up to 30% of obligate carriers of HPE3 gene in autosomal dominant pedigrees are clinically unaffected.
      Defects in SHH are a cause of solitary median maxillary central incisor (SMMCI) [MIM:147250]. SMMCI is a rare dental anomaly characterized by the congenital absence of one maxillary central incisor.
      Defects in SHH are the cause of triphalangeal thumb-polysyndactyly syndrome (TPTPS) [MIM:174500]. TPTPS is an autosomal dominant syndrome characterized by a wide spectrum of pre- and post-axial abnormalities due to altered SHH expression pattern during limb development. TPTPS mutations have been mapped to the 7q36 locus in the LMBR1 gene which contains in its intron 5 a long-range cis-regulatory element of SHH expression.

    • Sequence similarities

      Belongs to the hedgehog family.

    • Post-translational
      modifications

      The C-terminal domain displays an autoproteolysis activity and a cholesterol transferase activity. Both activities result in the cleavage of the full-length protein and covalent attachment of a cholesterol moiety to the C-terminal of the newly generated N-terminal fragment (N-product). The N-product is the active species in both local and long-range signaling, whereas the C-product has no signaling activity.
      Cholesterylation is required for N-product targeting to lipid rafts and multimerization.
      N-palmitoylation of Cys-24 by HHAT is required for N-product multimerization and full activity.

    • Cellular localization

      Cell membrane. The N-product either remains associated with lipid rafts at the cell surface, or forms freely diffusible active multimers with its hydrophobic lipid-modified N- and C-termini buried inside and Secreted > extracellular space. The C-terminal peptide diffuses from the cell.

    Answer

    Thank you for your call today, and I apologize that these antibodies still are not working.

    As we discussed, I'm sending a free of charge ELISA kit ab100639 on the order ***, which I expect to arrive by Friday.

    Please keep me updated about how this kit works for you, and let me know if you have any questions or if there is anything else that we can do for you.

    Answer

    Thank you for your call last week and for your patience while I have been in touch with my colleagues about these antibodies. I apologize for the delay getting back to you.

    The capture antibody ab87382 was tested at a coating concentration of 1 ug/mL, which corresponds to a 1:200 dilution as the antibody is provided at 0.2 mg/mL. If the antibody was used at 1:1000, this is a 0.2 ug/mL dilution which might have contributed to a weak signal in the ELISA. I would recommend decreasing the concentration of this antibody to 1:200. The detection antibody ab19897 was tested at 0.5 ug/mL, which is approximately the same concentration that you have used (the antibody is provided at 0.6 mg/mL for the lot that you have).

    We had also discussed testing the secondary antibody to see if it cross-reacts with the mouse capture antibody ab87382. Have you had a chance to test this?

    We do guarantee these antibodies to work in your assay, so if you think that they are faulty, I would be happy to send a replacement or issue a credit or refund if you prefer. Please let me know if you have any questions, and keep me updated about any progress with these antibodies. Feel free to call 888-772-2226 and ask to speak to me anytime.
