Protein attributes

Sequence length	700 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Modulates hedgehog signaling in several cell types including brain and lung through direct interaction with members of the hedgehog family.
Subunit structure	Interacts with all three hedgehog family members, SHH, IHH and DHH By similarity.
Subcellular location	Cell membrane; Peripheral membrane protein By similarity. Secreted By similarity. Note: The last 22 C-terminal amino acids may participate in cell membrane attachment. Isoform 2: Cytoplasm Probable.
Tissue specificity	Widely expressed in fetal and adult tissues. Highest expression in adult heart, liver and pancreas, and in fetal kidney. Ref.1 Ref.2
Domain	The 6 Cys residues of the EGF-like domain are arranged in a disulfide pattern different from the one found in the canonical EGFs. The function of this domain is unclear. It may be a binding site for other proteins or the docking site for a putative alliinase receptor By similarity.
Polymorphism	Genetic variations in HHIP influences stature as a quantitative trait type 12 (STQTL12) [MIM:612226]. Adult height is an easily observable and highly heritable complex continuous trait. Because of this, it is a model trait for studying genetic influence on quantitative traits.
Sequence similarities	Belongs to the HHIP family. Contains 2 EGF-like domains.

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]

Isoform 1 (identifier: Q96QV1-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Isoform 2 (identifier: Q96QV1-2)

The sequence of this isoform differs from the canonical sequence as follows:
     278-320: GGDERGLLSL...AIGPHDHILR → VGFLNFIYFC...NLAGENKGAT
     321-700: Missing.

Note: Potentially soluble form. No experimental confirmation available.
